I’m 22 and I’ve been on and off 20 mg of fluoxetine for the past three years and have had experiences with anxiety, panic attacks, and greening out in the past. I took a year break from fluoxetine and started smoking weed almost every day. Two days ago I started fluoxetine again. In hindsight I had 200 mg of caffeine and did an intense workout during the day. Right before bed I hit my pen and within seconds I was having trouble catching my breath and it felt like I was falling into impending doom. My thoughts started to turn into oh no I’m losing my mind and my brain is breaking. I genuinely was thinking I was never going to be the same again and that I was going through psychosis. I wasn’t able to breathe so I sat on the floor of my room and was doing breathing exercises (what I did in the past for panic attacks) but it just felt like no matter what I did my heart was racing faster and faster. My heart was pounding in a way I’ve never experienced before which led me to think I was going to have a heart attack. My entire body started to shaking uncontrollably and I felt freezing cold. I decided to call someone for help and they told me to only stare at one thing which actually was the only thing that was helping. For the next two hours I would go from feeling fine to my heart shooting back up and I’d freak out.
My question is was that really just a bad panic attack or something more? Also I’m now scared of ever smoking again and how would I know that wont happen again.
