hello!

i have a panic disorder that i thought i had under control because i was doing fine for almost 2 years. i went grocery shopping a few weeks ago and suddenly felt hot, shaky, weak and was seeing black spots. sat on the floor for a bit and slowely got out to breath some fresh air and since then my anxiety is always there. i'm scared to go out and feel really anxious before and while i'm outside. it's hard to take deep breaths, i always feel too hot, like my legs are made of jelly and i'm scared of passing out. 

i need to go to make a doctors appointment though because i have hypothyroidism and i need to discuss treatment with them but i am so so scared of going. i went to a bakery and the post office here to challenge myself and it went horrible. super anxious while going there, trying to calm myself down, going in, feeling okay for the first few seconds and i'm shaking, feel like i can't breath, high pulse and dizziness.

i don't know how to calm myself down and i'm on my period now as well which makes it even worse, since i have cramps and felt weak or dizzy while on my period anyways sometimes.

i really don't know what to do and how to get back on track
