marijuana causing anxiety?

Hello. About 5 months ago, i was over at a friends house and we were smoking. I cant remember if i was nervous or anxious while i was there, but i went home and went to sleep. I woke in the middle of the night in a panic state. i couldnt tell if it was from the weed or just me. I felt a pain in my back/ shoulder area and i felt like my collar bone had popped out of place. i also felt numb on the left side of my body. i thought i was having a stroke or becoming paralyzed. i felt like i would never play sports again and my panic grew worse. when i would close my eyes, i felt extremely dizzy and disoriented just laying down. even my vision out of my left eye worsened and my vision felt split. i woke up my mom and had her take me to the emergency room. i described my symptoms to them. i told them i had shoulder/ back pain and the left side of my body felt numb. they found it surprising that even my left side of my face and head and neck were numb. this did not relate to any specific disorder or injury. the final diagnosis was a muscle spasm in my neck. i was still in great panic. they gave me a vallium(a muscle relaxer) to treat pain and calm me down. they checked my heart rate 30 minutes later and it was still racing like it was before i took the pill. i left about 20 minutes later.

after that, i had was in a state of panic constantly. my heart and mind would race. i still felt numb on my left side and my left eye still feels heavy and my vision looked split. about a month later i told my mom i might have an anxiety problem. she set up an appt. with our doctor. all i told him was that i constantly am worried. one question he asked me was if i had been smoking any weed. i told him no. he prescribed me tofranil pm (an anti depressant) to take at night before bed.

after i began taking those, i would say my panic lessened to anxiety. ever since that night, i have not enjoyed smoking weed at all. sometimes, it would make my anxiety worse for a few days. my mind was always coming up with scenarios about how i could be made fun of or ridiculed. i constantly am paranoid about what other people think of me. i always believe the scenarios i make up are true and i beleive i know what other people are thinking about me. i became very quiet( i was shy already). i felt mute most of the time, especially when i was high.

my friends are frequent pot smokers. i have lost contact with them because hanging out with them involves smoking weed. even when i am with them, i harldly have the courage to say anything at all. i think i have lost my self confidence and esteem. i really have nothing to be ashamed of about myself. i am 6'5" a muscular 220 lbs i play football and basketball, girls find me attractive (even though since freshman year i have not began to become friends with many girls.) im not gay, im sure of that. im often afraid to speak in a large group of people.

i used to enjoy smoking weed alot until that one day. my entire life has changed since that night. this is my senior year, and ive never been more unhappy in my life. can anyone help me? thanks for reading
