I have two sisters - both got married and had children at a very young age. When I was the age they got married I dated for the first time. If all's said and done I got into a relationship because I felt awkward, people (friends and family) got worried whether I will ever find anyone. No, I am not blaming them ... I am blaming myself for giving in to that. Needless to say, the relationship ended after 3 years. I did not get married, so no divorce and I moved on with my life. Packed up, went to a bigger city and concentrated on my job. Life was beginning to feel good and I decided not to get into the same "trap" of thinking I need to get married before I reach a certain age.
Then I got saved and that changed every thing.
I got around, travelled and lived in different countries. I was free - my sister tied down with kids and husbands. Their words, not mine. They would love to but can't go to places. The same sisters who scorned me, ended up a decade later feeling envy. They love their kids, it's not that they resent their husbands or kids ... but they realize they could have waited and take care of their education, their career before rushing into marriage. Being married, taking care of kids and then trying to study in the late evening so that they have a chance at a job once the kids are old enough, is not an easy task.
You need to make up your mind: you want to be married and pregnant now or you want to wait for the man God wants you to have as a husband and father of your children. If you decide the latter (waiting on God) two things will happen: you don't feel lonely and you won't be depressed. Feelings of loneliness and depression enter when you start getting frustrated because God does not do what we want Him do when we want Him to do it.
