Lately my anxiety has been really increased due to going through Vyvanse withdrawals as I wean off of the medication. In addition to that, I recently had a panic attack that landed me in the hospital when I consumed too much caffeine. During that experience I genuinely thought that I was going to die and since then I've been a lot more prone to panicking and thinking that I'm dying/about to die when there's no logical cause, especially while I'm driving. It sounds crazy, but I can't even let myself relax because I'm afraid that if I let of control that I'll die. Has anyone else ever experienced something like this?
