I dont know whats happening. To me.

Hello, I have had panic attacks since i was a teenager. But then after my dad's death, i consulted a psychiatrist and had alprax for 6 months and it was cured fully. For about 10 years i was fine. After i got married and 1 year later my inlaws visited for 6 months that time was very stressful. the relationship between me and my mother is also very strained so I was all lost and suddenly i started feeling panic that i might not sleep properly this was a very bad phase and i had nexito from a doc prescription for 5 months and was fine again. I got to know that i was pregnant so there was no scope of medicine and during pregnancy again my in laws came and all the verbal torture started again. I was unable to sleep and panic that I won't be able to relax racing thoughts. after the  came i was happy for three months but again that heavy feeling in chest and sleepless and melting feeling as if i am going crazy has started. i cant stop thinking small things. what is actually happening to me.
