Just weird

I don't mean to sound all depressed and stuff but lately I've just been feeling down and it's getting a little harder everyday to stay positive. It's hard talking about this time other people and I'm afraid to talk to others and I thought it would be easier to talk about it here with other women...I also find it hard to talk about it with my boyfriend. We've been together for almost 4 months and I have huge trust issues (typical). So to cut this short, help....
