I could give a lot as advice, but unless it's technical or legal I'm somewhat of a buffoon. Engineers are sometimes socially left out, and I'm a classic case where the gender conflicts in my youth made the social anxiety even worse.
But to go on, I was also a loner in my old male life, and that background made it crippling when these damn hormones kicked in.

. Like you, I suddenly want and need contact with living, caring people who are friends without question. And I also need women who understand what it means to be transgender, and can share in the trials we go through. After so many months of avoiding group situations I've found so many women like me in group therapy, and the girls my age in these groups had similar life experiences. They've also felt left out, abandon, or forgotten, and mostly alone when everything goes wrong. I call it being invisible. Yeah, everyone sees us, and hears us, and they still pretend we're not here. So I go to group therapy because women my age are there, and we share a lot. The few old friends I had disappeared, and new ones are taking their places. Yet to my surprise a few of the cis women I used to work with email me regularly now, and we gossip. Yes, Gossip.
Anyway I love my group sessions, and before coming up to Michigan for the summer I couldn't wait for Tuesdays to roll around. I'd speak with the older girls most, but the young girls are so smart these days, and are way ahead of anything I could have dreamed of at their age. And hey, it's also a great way to find people who want to have a small group lunch or dinner. So it's not all serious, and overwhelming. There are real people out there.
Sorry this may have rambled a bit. And if you ever need to talk you have my number.
Take care. Kathy
