Am i going nuts or whats going on???

Ok. heres my story about 8 months ago i went to the state football tournament and the night before the games i got pretty drunk off of jack daniells. the next day i had a pretty bad episode where it felt as if my body went completelly numb while sittin in the stands. This freaked me out and sent me into a panic, i didn't know what to do and i was just going crazy inside. well anyhow that night i had a terrible ear ache and my ears started to crack. Well ever since that night i've been having this ear problem where my ears will crack and crack when i move my jaw. And besides that my anxiety is horrible i went a whole week without being able to sleep. i feel tired and have no appetite. Its really starting to scare me. But i did go to an ear specialist, and had a cat scan done and he told me everything was normal but it sure don't seem like it. then i went to my doctor and got put on celexa for my anxiety. however i still don't feel quite right. There will be times where i willl be fine and then all of a sudden i feel a bunch of pressure build up inside my head and then i get real nervous and jittery its like i can't sit still and slow my thinking down i think faster than lightning. i just don't feel my self anymore, my mind just don't feel like its working right, and i don' know what it is, brain damage??? am i going nuts???? or whats going on with me????????????? please help me i don't know what to doooo if you wanna know any more about the story,, just ask?
