Rosa, you'll be in my prayers. I have dealt with the same thing.
Breakups, a bad relationship with my father, and the mix of pot and alcohol almost lead me to suicide. i used to sit around and daydream about it, just to see if i could test myself out. the only time i ever did "attempt" was to drive my car off the road and hopefully wreck and die. oddly enough, all i ended up doing was swerving on the road, and kicking the dash and crying. i also looked at knived and quickly pondered the thought, but then something drew me away.
as of right now, i am still batteling my own depression. i am batteling a struggle with alcohol which now has lead me to getting an OVI (basically the same as DUI), and knowing that the struggle/addiction is still there. sometimes i have wondered what is the point of going on like this, no matter if i am a Christian or not. my past shows a lot of failures, and i have debt on me, and now i have this drinking issue coming to head, and i am alone, single through this, and sometimes it is like, what is the use anymore? my past sins still haunt me, because they range from many areas. i have quit my pot use, it's been 4 going on 5 years now, but still i feel worthless at times and my own depression kicks in a lot of times.
nevertheless, in our despair God is at His strongest. i know that doesn't always help, but it's something i have forced myself to believe and accept and nevertheless, God has brought me through a lot of my own nonsense that i have put myself through and been through. just remember you are precious in God's eyes and to others eyes. you are precious period. people care enough about you to keep you in prayer, and you will be in my prayers also. please talk to me private messages, or email, or if you have instant messaging. whatever will work if you need someone to talk to. hope is one step at a time. but taking that first step and keeping on it, shows you have strength inside of you. knowing God is still there, has helped me out soooo much. the beauty of God loving us when we may be losing our faith, struggling, at our wost moments, has been so vital to keeping going. plus, find the people around you that really do love you and care for you UNCONDITIONALLY. the love my mother has literally saved me, and if you want to know more of that, send me a private message, for i don't want to bagger this post anymore with things about me, for your need is what is most important when addressing your issue.

May God Bless you Rosa, and again, please feel free to take up my offer to email me, pm me, or if you use any instant message stuff, let me know and we can talk that way too. again, May God Bless you! <><
