Social anxiety/ making friends

It is SO hard for me to make friends. I have social anxiety AND a resting bitch face. So I just look like I’m mad all of the time so no one ever talks to me... at the same time I don’t talk to anyone that I don’t know because I have social anxiety. This is making me slip into a deep depression. I have no real friends that actually want to hang out with me. It is near impossible for me to make girl friends, but for some reason it’s very easy to make guy friends but my boyfriend doesn’t like the idea of me hanging out with a guy alone. (Which I completely understand because I’d be way jealous if he was hanging out with a girl alone). I just don’t know what to do anymore I get lonelier and lonelier every day. My boyfriend hangs out with me a couple times a week. Other than that there is no body else who is really there for me. I just want a girl best friend and I just don’t know how to do that :((((( any advice at all? I am so stuck. Every time I talk to a girl I get really nervous because I just want her to like me so we can be friends but then I make it awkward some way or another and freeze up and the convo ends and no new friends are made. I am so lonely it’s killing me. I just want to get out of my house and laugh with my girlfriends. I miss it.
