I feel so alone..

Today I am 7 weeks pregnant. I am healthy, take my vitamins, my first dr app is this Thursday.. However, I have no friends anymore, my "baby daddy" is at the Center of Hope which is a rehab. I love him so much he is my best friend. He has a problem smoking spice, a very bad problem that has caused so much damage to our relationship.. he has been smoking it for almost 10 years on & off.. I don't know why I miss him or anything bcuz he lied to me all the time. I didn't even know he was still smoking spice.. My parents haven't been very nice to me. I want to be so excited ab being pregnant but all I do is cry everyday.. I'm so scared that I'm going to end up having a miscarriage bcuz of how upset I stay all the time.. I have no one at all...
