Panic Attack

So I know I've had some form of anxiety since I was a kid, I always had to have control of situations and if someone messed with anything I was working an i would get so stressed out by the situation I'd have to leave. (Makes me think it might also be OCD because a lot of my stress came from people moving stuff out of where it should be, touching me without me knowing they were "clean" or "healthy", or people not letting me finish something at a point that felt right) As I got older I began to have intrusive thoughts ALL the time, like I'd be cutting vegetables and get the thought of me accidentally slicing my hand open and it would make me unnecessarily stressed for the rest of that activity. I get those with almost everything I do now. My main question is about a certain panick attack symptom. I get really bad panick attacks about the times a year, symptoms are hyperventilating, dizziness, nausea, weakness, chills, shaking, absolute dread, uncontrollable crying, and sometimes vomiting or fainting. It usually lasts about an hour and for a day after I feel beat like I had just run a massive sporting event. I have found no link with these panicked attacks to my menstrual cycle, or any increase in external stressors above my baseline, they seem to just happen. The symptom I am curious about though always happens a day or so BEFORE the panic Attack. I get this wave of absolute euphoria, I feel unreasonably happy, I feel hyper present and in the moment, any pain I have is gone, I feel aware and comfortable in my own skin, and unnecessarily giddy. This usually lasts about 20 minutes and fades away, liked clockwork I get a panick attack about 24 hours later. I really want to know what these euphoric/panick episodes are, they don't happen often but they are so intense. Thanks in advance.

I have severe panic attacks myself. However I can’t recall having that sort of euphoric episodes. You should do some researcher and see some doctors because excessive mood swings and euphoric manias are main symptoms of bigger mental disorder such as Bipolar disorder. However, you are probably afraid of panic attack can happen and your brain and overthinking will increase your anxiety level and result in having panic attack.
