Emotional

I'm wondering if anyone else feels like this or knows what to do?

I get so emotional over everything to the point where talking about anything serious about how I feel or something bad I get upset and cry.

I'm really sensitive as well get upset over things I shouldn't, overthink stupid things and get upset over that.

My boyfriend is starting to get frustrated over it as he feels he cant tell me anything without me getting upset.

Can anyone help me?
