<human>: Can you condense the text into a few key points?

Is this normal? I'm getting hit with depression, feeling lonely without  a solid social circle. I lost mine many years ago after not staying in touch due to some real bad depression and anxiety...
 
 Gf and I don't really have many friends, we've lost touch with many, and spend most of our time just with each other when we hang out. I have a problem developing and sustaining authentic friendships. I am introverted by nature, once I feel someone has labeled me as quiet or introverted I find it hard to be myself around them. I'd like to have a better social life (doesn't matter if it is just me or my gf also included) but find it very hard to develop into a regular socializing/hanging out routine with people when everyone already seems so solidified into their groups. 

Appreciate any advice as I'm getting tired of the routine. Jesus who would I even invite to my wedding?
