Thanks for letting us know what happened, I'm very glad you have sorted out the social media problem in such a simple way and also that you were able to talk to the councilor and your friend - did you find they helped?
I guess I understand what you mean when you say you worry about super obscure stuff. I sometimes think my mind is determined to do some worrying, and then simply picks on something as a subject, unpredictable and no real reason why.
That kind of makes it hard to come up with solutions, or even explain it all so others understand. Still I found my best way out was trying to get to the bottom of it all -the anxiety condition itself. As my stress levels improved my anxiety became less.
The sorts of things I do are exercise (when I can), eating sensibly, getting as good a night's rest as possible and trying to avoid things I know are going to make me tense up and stress. That means some people, some situations, and even sometimes things like the news. You can't get rid of everything of course, but even a bit less counts.
I also have this idea that if I have something to do each day I enjoy, and it is the sort of thing htat takes my mind away from the hassles of life then that helps a lot. I use books, movies and pets (their names are Sumo Cat and Nasty Cat). Sumo is the relaxed laid back cat, Nasty is, well ... nasty.
All this gives me something to look forward to each day.
