Anxiety after smoking weed?

Okay so i smoked weed for the first time at a party but i only took two hits and i did not feel high and then one month later i smoked weed again only took two hits and i did not feel high again but that night i got drunk for the first time as well. (With four beers to be specific) i went to bed that night and everything was okay until about 4am i woke up because i felt sick so i went to the bathroom to see it i needed to throw up but nothing came out so i just went back to bed and felt fine for the rest of the night. The next morning i woke up and i felt very weird i can't quite pinpoint the feeling but it was weird and i would get mini anxiety attacks for the rest of the day. Along with that i would also kind of feel out of breath when i was sitting down or just walking but i ignored it. That night i felt very sick and i felt a feeling around my chest area long with anxiety i also kept feeling like i was gonna throw up and by body would suddenly get very hot. Then i got a big anxiety attack that lasted about five minutes. I just thought i was hungover but when i asked my friends they reassured me i only had four beers and 20 hours later i should not be feeling hungover. For the next three days everything was normal except for feeling out of breath a lot when i was doing simple activities. Then a few days later i was laying down on the couch watching a scary movie with my family and suddenly when the movie got very intense i got a huge anxiety attack which caused my heart to race and me to feel like i was on the verge of passing out. Afterwords i felt very tired so i fell asleep but then again in the middle of the night i had another anxiety attack. Ever since that day i have not felt normal again. I always have a sensation in my chest that causes anxiety and depression. It has been a year since that day and i can honestly say i have not gotten better. I can not watch scary movies because my anxiety gets the best of me i have lost a lot of my friends because the depression has caused me to be uninterested in everything around me. I used to be such a happy person and so full of life but now i cannot remember the last time i was happy. I always try to focus on the positive but this feeling of anxiety has taken over my life. What can i do and what could this possibly be?
