single , pregnant and depressed

hey. I know a little how u feel. Me and my ex were doing amazing. we had talked about having a baby and 7 months later i got pregnant.........found out 3 days after we broke up! He started messing around with pain pills and started to get addicted and everything changed, he changed. I already have a 5 year old from a loser that is uninvolved and doesnt help at all. I thought i would actually marry this guy im pregnant by now one day. The pregnancy couldnt have happend at a worse time. Im so terrified about being alone pregnant and having another loser baby daddy. Then i think about me and my kids future. how many good men want a women with two kids by two different guys. Its so depressing and im starting to resent the pregnancy. Im only 6 weeks, and i honestly catch myself almost wishing i would lose the baby wich sounds so horrible! idk what to do. The worst part is dealing with the break up and sitting in the house with my five year old while he is out living it up like nothing has changed. Its not fair how many men do this to women! its like a life sentance. dont get me wrong my daughter i have now is my world. and i work hard to provide for her and give her a stable home.
