I've been there before. I used to feel totally crazy. I just wanted to feel like myself again when I was younger. Are you seeing a psychiatrist? I know it's hard to reach out and get help, but it's so worth it when you finally feel better.
You seem like a really cool person and I think you are normal. Anxiety is normal and very common. It might take a lot of trial and error, but it's totally treatable. I guarantee you won't feel like this the rest of your life.
Sending you my most positive vibes.
May the wind be always at your back.
