I know how u feel about panic attacks. Altho i never got them while i was having my treatment for IVF, i started to get them about 10 years ago while taking zolodax injections to treat my endo. They are the most scariest thiings i have ever experienced. I tried all different sorts of treatment for my endo, but ended up having nothing because of these attacks. I remember telling the DR about it and him saying u need to relax la bla bla, i dont think he beleived me untill i had an attack the day he was injecting some zolodax into me. I also had a heart monitor which i had to press each time i had a palpatation, or an attack.
It showed up nothing, no problems with my heart or nothing. It took me a a long time to realise that i wasnt having a heart attack and i learned how to control these attacks (by now i was getting at least 3 or 4 a day) i would tell myself that there is nothng wrong with me, that im not having a heart attack and i take deep breaths slowly and try to think of other things, i know its not easy thing to do, i still get a bit panicky now and again, but i WONT allow myself to get back to where i was 10 years ago.
I came off all medicines in the end because i felt it was having an effect on my life, and after about 3 mths i felt a lot better (altho the period pain was and still is really bad each mth) i would rather have the pain than have the attacks. I was afraid to take the hormonnes again when i started IVF, but i was ok - i think u are having these attacks while having treatment - 1, Because of the stress u are undes and 2, The hormonnes u are taking are making u feel paniky, this is why after ur treatment u feel ok.
I know its easy for me to say, calm down and learn to relax, its not easy done is it when ur in this situation, im sorry ur going thru this, its not nice i know - but beleive me, you can teach urself to relax, take a warm bath, read a book, do what u feel comfortable doing. Once u have ur heart monitor and the DR tells u that nothing is wrong, then maybe u will start to feel more comfortable with each attack and learn to control this. Like i said, i still feel panicky in certain situations (mostly crowed places) i even went to a concert a few weeks ago and started to feel paniky incase i had a panic attack in front of all these people lol, its silly really, but its what we feel and it cant be helped.
I do hope u can learn to control these attacks, please remember, there is nothing physically with you, i hope i havent offended u in any way, and i do hope u get ur BFP and start enjoying the process of becomming a mumy
