Shaky legs symptoms and conditions

Hi Everyone,
After reading all these posts, I am just hoping that this pill caused me all my problems.
Back in march i had what I could now call a panic attack.. I started sweating and thinking i was going to faint and die.. I managed to run to the coffee shop.. and after a chocolate and few mints resting I was ok..so i thought my blood sugar may be low..... during April and June i could feel my legs very week...i thought i was not eating properly.. so ignored it..At the end of June on my third day of holiday I got the same feeling as i did in march i thought i was fainting and dying...After this episode I had shaky legs all the time..thinking i could faint at any time.. my heart was beating very fast once a day.. I had a blood test done just for thyroid and it was ok... after three weeks of thinking i was dying inside I started feeling very strange like if it was not me.. I was anxious..scared of my dreams..scared of my thoughts.. very anxious in the morning....feeling like i was in a dream and disconnected from my body.. I stopped the pill and it has been two months..i could say i probably got 5% better but i still not feeling like this is my body and my life..feeling I am going crazy.. i am not able to think properly..some sort of brain frog..it feels like if i didn't exist in this world..It has been horrible...headache everyday however I dont know if it is my anxiety or if i have something in my brain..

I just hope this feeling goes away and i can come back to be my old self... i used to love life ..every bit of bit...with bad and goods.
