Feeling stressed

We live four hours from my family and home city and I have been having the hardest time. I have a nearly three month old and I'm in a place where I hardly know anyone and the ppl I've met I don't like or trust. We live with my husbands family so we could save up some money and move and finally get a place of our own. In the last month I've gone from happy to every feeling in the book. I've gotten depressed and I'm what to do anymore. I'm how to stay happy for a long period of time. My little girl makes me smile but I feel so alone. My husband helps alot when he can which I'm grateful for but I cant help but feel like there a no light at the end of the tunnel. We've had a hard time financially for a long time. I'm just so stressed out. I just really needed to vent.
