I'm feeling depressed

Recently I have been loosing lots of friends and i don't know who to talk to.

My boyfriend (we are long distance) said that i should go out more and make new friends but I find this difficult because of my anxiety.

I tried talking to my best friend about it but she just tries to avoid the subject because she is one of the people that doesn't invite me to things and talks about them in front of me.

I'm stuck in the house most of the time and i'm starting to feel trapped because i don't know what to do with myself and I just need some guidance on what to do.
