I am so stressed!

Nowadays the silencer on my cell phone has become my very best friend. Its nice how I can just block out the noise of my phone when someone calls me that I dont want to talk to. Now if only life had the same features...huff. Being growup sucks because I know thus far in my life I have made a lot of wrong choices and if I am indeed pregnant these wrong choices will not only affect me but my child as well. Its amazing how one sin can just ruin so much. You fall into fornication and boom your faced with the possibility of becoming a parent and the difficulty of know if you are will you or will you not tell the guy. He is so unstable and has no job at the momment. And on top of all of that he is an abuser, will I allow myself or my possible child to fall into that kind of lifestyle? NO! So what do you do? Who do you turn to? Mother dosent listen, father dosent need to know, Sister will tell mother, so who can I turn to no one but Jesus. But how to you approach the HIM when you know you have disobeyed time and time again, I just feel so guilty I feel so alone. I just dont know what to do. If I talk to him will he hear me? Will he respond to his child who has strayed so very far away for Godsake I surely hope so.
