Slight rant, just need to get it out!

I'm 21 years old and 17weeks 1day pregnant and I feel like I'm slowly losing my mind and myself. I currently live with my SO and his family (moved out from my mom unexpectedly) and it doesn't bother me. Living with his family isn't part of the problem, it's actually helpful at the moment. I just feel like a burden to his family because I can't find a job and can't help out the way I want to. Most days, I won't leave our room because I have nothing to occupy my time. I really don't have any friends so I have no one besides my SO and his family to talk to. Don't get me wrong, I can talk to my SO about any and everything but it's just not enough. I am happy about starting a family with because I really do love him. I just want to be able to help him financially and give him the same support he gives me. I'm tired of crying myself to sleep at night and becoming a loner. I just don't know what to do at this point in my life.
