so some very short background: this time of the year (august) is very hard for me due multiple different traumtic reasons. i've dealt with anxiety and depression and PTSD for over a decade but lately I've been having what I think is anxiety but manifesting itself differently than usual? 

last week before bed i suddenly got super restless, legs shaking, heart feeling weird/tight? idk how to describe it and i just felt general unease. i had to put on a comforting movie to help myself eventually pass out and the next morning i felt fine. 

then, last night i got the feeling again but worse.  took me even longer to finally fall asleep and now this morning i still have the weird feeling in my chest and sense of unease. 

I'm worried something is actually seriously wrong with my heart but i keep trying to tell myself that's catastrophizing and the signs point to anxiety (it's worth noting it's around this exact week something very traumatic happened to me) and it'll pass and I'll be ok. i did make a doctor appointment but i'm on state insurance and the clinic is booked out until november :/

i could just really really really use some kind words reassuring me this is normal and I'll be ok or giving me their opinions on what I'm feeling? i just don't understand why my anxiety would suddenly manifest itself differently after a decade? 

thanks in advance :(
