Hi DiDi,
I'm glad to hear your time off social media is paying off; as somebody who grew up when IRC was all the rage, playing MUDs was cool, and Kevin Mitnick was about to become famous, and father to a 15yo girl, I see the terrible psychological damage Facebook, Instagram and Co can, and actually do. May I suggest you stay off them until you are back to a rock solid state of mind?. I'd keep only the ones used strictly for communication e.g. Whatsapp, Signal etc...
Having been at the mercy of depression as well, I know keeping supportive people around can make all the difference, so I'm very happy that you have found your cousin to be an ally. Keep her close, and do try to make an effort to meet your friends; it'll be difficult at first but I'm sure once you see them you'll think "why didn't I do it earlier?" .
It's great to se your doctor is so supportive, I hope if/when I transition mine is as nice as yours. And remember, you have plan, keep focused on it and you will eventually get there, whether it takes 2 months or 6 or 12 doesn't matter, what matters is that it gets done.
Hugs,
Sonya
