Hi Ladies
I'm reaching out for help as not in a great place

So I'm 44 & not noticed much on the peri front up until maybe now?
So I noticed i was getting an increase in anxiety the last couple of months.
Around 7 weeks ago out of nowhere I had a adrenaline surge just watching tv, followed by waves of them all night and pins & needles..
Saw a nurse next day. Had all the tests including a mini ecg & bloods but nothing wrong.
2 weeks on these feelings everyday, very awful & scary & fuelling my anxiety even more..
After 2 weeks upon going to sleep my body woke up to this awful feeling of faintness with waves of adrenaline/ pins & needles, ears ringing, literally awful. I even called 111 & contemplated A&E. This episode lasted all night. Next day bk to the on & off head surges. Next night 4am wake up to another I believe panic attack but much worse, I thought I was going to have a stroke. Heart wasn't racing to bad I think about 115bpm but my head was gone, rushes, dry mouth etc & feeling faint. I saw 2 doctors who hadn't a clue. They just said all my vital checks & bloods fine. Things persisted pretty bad that week and again no major help from doctors. I booked myself in for a private MRI as couldn't believe how bad I was getting. I had some sort of a panic attack there too. Results came back normal. I paid for more advanced bloods but again showed up nothing. I tried hrt 3 times now but find the estrogen even on a very small dose gives me stronger surges & jitters..
I'm very low right now, have no idea if this is Peri or what? No answers from doctors & tests all clear. I feel consistent anxiety. I feel adrenaline surges through my head daily. My brain just feels awful. Pins and needles, almost like not enough blood to the head feeling. Sleep very on & off and find the nights the hardest & mornings with these feelings..
Please Please Help if you've experienced anything like this or similar and the outcome, help or medication
I haven't even been out the house except for dog walks ..
