Anyone here with hyperthyroidism?

Ever since a year ago there’s been a huge change in me (physically and mentally). I’ve always had anxiety but it was pretty controlled. A year ago it became constant and out of hand. I would get anxious for no reason. Anxious to even go to the store. Anxious 24/7 basically. I would have constant anxiety attacks. I also started getting tired constantly. Even when my day wasn’t that tiring, I would feel weak and tired. I still have the random anxiety attacks and still feel tired and weak almost every day. My random weight loss has also been a factor that has made me wonder if I have a thyroid problem. I eat the same or sometimes even more and I’ll lose weight. Does anyone here know if I might have hyperthyroidism? I’m getting a blood test done this weekend to know for sure but I wanted to see if I could find someone going through it. Also, what kind of self examination could I do to check? My doctor put his hands on my neck and made me swallow but he didn’t say whether or not he felt anything, he just had me keep doing it.
