Hiya (yes, I disappeared again, sorry).
I'm glad to hear you're comfortable talking to your therapist. The best way to get the "help" we need is to just lay it all out there, so I'm glad you've got someone to do that with. And I'm happy to hear your parents are supportive of your journey towards being your true self. I imagine it's no small thing for you and I hope you're met with lots of love and acceptance, as you deserve. Is there any firm plans in place yet for going to see your grandparents? Or is it still up in the air?
I'm also wondering if you've talked to your GP about medications? If that's something you think might be helpful for you too. It might level things out for you if you're really up and down. If you're not into medication there are other things that can be helpful to, to try and relieve symptoms of anxiety. You can browse the forums here to see what works for other people, or again, talk to your GP or your therapist. I do meditation, exercise, yoga, deep breathing etc. It's really about finding what works for you. All of that can be really hard when you're not in a good mental space, but they really can be helpful. I know you mentioned you like reading. I wonder how you feel about writing? Maybe doing a journal/diary type thing will be helpful in getting your thoughts down and helping you to work through them?
As far as your social life goes, I find when my mental health isn't great, that human interaction is tiring. I deal with it better when I'm in a good space. Can you relate to that? I wonder if it would be helpful to try and get involved in social things that aren't too intense, so you aren't missing out completely, but you're also not overwhelming yourself? You said you get out and play Ingress sometimes (I'm not familiar with that, but I used to play PoGo). What other sort of things do you think you might enjoy doing that will get you out and about a bit more? BTW I think it's really cool you're into Politics. We need more young people interested! Good on you.
Kind thoughts, Katy
