Why does God allow certain things to happen?

Jeremiah 29:11 states that we have a hope and a future, despite the bad circumstances we're facing. Well in my situation an irreversible thing has happened and has drastically shaken my confidence as a person. Something that has affected the way I look, although it's a natural thing... ok I'll spill it, I'm losing my hair. Now I'm in my mid 20's and I know it is not highly uncommon for this to happen, but I've waited my whole life for the women God has planned for me(I literally never even dated someone b/c I was confident that the Lord would let it happen when it was ment to be). And now I feel like I'll never have the confidence I once had to break the ice with her when our paths finally do cross. I have become quite self concious and I pray about this all the time and am constantly looking up scripture to cope.

Why? Why? Why? I have to literally fake my confidence now and even force myself to look into people's eyes b/c I feel like they are stairing at my head. I guess what I'm trying to say is that I don't understand why God would allow this to happen to me when He knows how greatly it breaks my heart. I'm not shallow or vain by any means, I mean come on, who wants to lose their hair?? People tell me that God does things like this draw us closer to Him so we fully rely on Him for His promises.... well I do trust Him and still think I will meet her when God's timing comes into focus, but I just can't grasp the whole idea of my shattered confidence. I can't imagine a girl my age not somewhat feeling turned off by me losing my hair at our early age. I know this can seem like a shallow concept but it's reality and it hurts. Please someone give me a Biblical reason for all of this. Why has God allowed something that hurts so much. I have served Him with pure motives and Love Jesus so much and would never never let this effect our relationship, I just need encouragement and a somewhat clear answer.

Near China's northern borders lived a man well versed in the practices of Taoism. His horse, for no reason at all, got into the territory of the northern tribes. Everyone commiserated with him.
"Perhaps this will soon turn out to be a blessing," said his father.
After a few months, his animal came back, leading a fine horse from the north. Everyone congratulated him.
"Perhaps this will soon turn out to be a cause of misfortune," said his father.
Since he was well-off and kept good horses his son became fond of riding and eventually broke his thigh bone falling from a horse. Everyone commiserated with him.
"Perhaps this will soon turn out to be a blessing," said his father.
One year later, the northern tribes started a big invasion of the border regions. All able-bodied young men took up arms and fought against the invaders, and as a result, around the border nine out of ten men died. This man's son did not join in the fighting because he was crippled and so both the boy and his father survived.

the world is always concerned about,how u should look,what you should wear,and all those relted things,but god only cares about whats in your heart and what are your motives,when you constantly think about what the others are gone think about you,you become a slave to people,free your self from people and be a slave to the holy spirit,after all god is in control.

Freeport, thanks as well. You always seem to give long replies, which I'm grateful for. I know you don't know me personally and would seemingly wonder about weather I really trust in God, and let me tell you, I do with the faith that was given to me. As for my confidence, I can guarentee you that if you were to ask someone who knew me (co-worker, friend) they'd tell you I was a confident person, despite my condition. The thing is.... I fake it. I know I should be confident in the person I am in Christ. And I know how God views me (my heart) but regardless, I am human and struggle with my self image to a point. I pray all the time for confidence with the right mixture of humility so I wouldn't get full of myself but rather be motivated to get out there and serve God. Anyways, thank you and God bless...

I sometimes wonder how Satan did not indirectly kill Job as thoes things he had are not luxurys they are required for life (food, shelter, etc). Once all of his stuff was burned up and he was battered its a wonder he did not come down with an infection or die from exposure because all his assets were destroyed or starve to death because his cattle was gone. Im not sure if it says that he died shortly after that had occured, Satan may not have killed him right then and there but it would not surprise me if he did not die very shortly after. We dont build houses and raise cattle for no reason its becasue the natural enviornment is brutal and does a poor job of sustaining human life. Back then it was much more burdensome to rebuild or reraise cattle and he may not have even been able to do it.

10 After Job had prayed for his friends, the LORD made him prosperous again and gave him twice as much as he had before. 11 All his brothers and sisters and everyone who had known him before came and ate with him in his house. They comforted and consoled him over all the trouble the LORD had brought upon him, and each one gave him a piece of silver [a] and a gold ring. 12 The LORD blessed the latter part of Job's life more than the first. He had fourteen thousand sheep, six thousand camels, a thousand yoke of oxen and a thousand donkeys. 13 And he also had seven sons and three daughters. 14 The first daughter he named Jemimah, the second Keziah and the third Keren-Happuch. 15 Nowhere in all the land were there found women as beautiful as Job's daughters, and their father granted them an inheritance along with their brothers.
16 After this, Job lived a hundred and forty years; he saw his children and their children to the fourth generation. 17 And so he died, old and full of years.
