The pill

So I got on the pill about 2 years ago and since then I have gained so much stubborn weight that I cannot seem to lose no matter what I do! I'm also more moody. I am always down. I'm not depressed or anything but that's almost what it seems like. I've isolated myself from friends and family. My boyfriend is the only person I ever really even talk to anymore. And this all started 2 years ago when I got on the pill. What do I do?😭
