I totally feel you...
I used to be very social and am a natural extrovert.
So being so socially anxious really takes it toll on me.
I'm literally afraid of people, what should I say, what are they thinking of me, do they like me??
All these stupid doubts and fears, I hate it. Makes me feel sooo lonely and we need good relationships to be happy. Its in our DNA and when that's not there, we become sick. I hope you feel better soon because being like this is just not fair and you deserve to feel connected and not alone.
