Anyone else feel like this after breaking up?

I got broken up with recently, and along with every regular feeling you'd have about it I just feel like disappearing. I mean, leaving everyone in my life and distancing myself from everything I dont want anyone to hear anything from me or the other way around. Maybe it's because I feel betrayed but I just can't shake off the feeling and just stay home or leave and go somewhere far from everything and not answer a single message or call. I've been depressed in my teen years (probably still am, I just think i'm not) and have a past of sh, I haven't felt this way in so long and i'm just so, so bitter. My boyfriend was the only friend I had and I dont have anyone to turn to about my feelings and seeing him have so much support and even a new girl around makes me so angry.
