I have anxiety nd it's gotten bad at this point, a lot of times I'm just sitting on the couch nd I feel fine but a sudden wave of anxiety nd starts panicking nd shaking my leg nd just overall worrying for no apparent reason.

Sometimes it happens in classes nd it's terrifying, I try to do breathing exercises but they don't seem to work as well, It feels so embarrassing nd like everyone can tell. I've talked to a therapist ab this in the past but not a lot. 

Does anyone have any tips on how to manage this? Or even if anyone else goes through this too? I've asked a couple of my close friends who as well have anxiety but they don't seem to relate to this, I feel like I'm weird because of it.
