If it happens once in a while then benzodiazepines would help against the anxiety attacks but if you say it´s every day I wouldn´t choose that method.
You say it´s because of exhaustion so it seems you have narrowed down what the trigger is that is good at least, I myself have finally after years found out I need to (in lack of an english word) energy calculate so if you start noticing you get too exhausted like your nervous system is starting to go into overdrive then take a break maybe sit or lay down and watch some TV for a few hours it helps my nervous system to calm down even though it sucks, it even means I will have to not workout that day or not even play competitive video games because it is also exhausting even though I like it.
Of course I don´t know anything about you, do you work a lot or do a lot of physical activities or play competetive video games? You mentioned social situations those are straining on me too so unfortunately that is something you have to limit too so instead of spending e.g. 8 hours with friends or family then maybe limit it to 3 just an example.
It seems like we're in a similar situation regarding panic attacks and social anxiety. My problem iwth panic attacks is: everything that reminds me of them triggers them in social situations. Meaning if I get hungry, I'm warm, I#m exhausted, dizzy,nauseaus etc.
I worked out a lot, but couldnt anymore in the months leading up to my stay in the clinic. And yes, I also play competitive videogames. My problem is I cant take a break in the clinic, because I'm constantly in a social situation and I cant escape.
Then don't go home. If you have a panic attack, speak to the nurse, you probably have some medicine "in case of panic attacks" that the nurse is allowed to give you. If not there's a doctor on call.
Mind you, there is a difference between feeling nervous and having panic attacks. True medical panic attacks end up lasting a few minutes only (they seem forever) bcs the real, strong panic attacks make you unconscious quickly.
I also get them in the clinic. They dont have medicine for me because I took 1-2mg xanax a week to function at my job. The panic attacks itself are around 8/10. I didnt need to vomit, but my heands are shaking, I'm sweating, it feels like my heart is beating out of my chest, I'm incredibly nauseous and I get very strange skin sensations.
They are over in around 15-25 mins, but then I get the next one 10 mins after because of the exhaustion.
