Scared of Shrooms

I thought I was discovering something amazing. My friend got me onto them and I loved the experience. Took 1.2g, and tried 1.8g with other friends. Culminated in me revisiting some old friends in a park at night and I took 2.3g before I showed up and then it kicked in about an hour after I parked. At first it was amazing but then I started to feel an overwhelming sense of fear as I lived out wild catastrophic possibilities of us getting caught, me overdosing, letting them walk onto a busy road nearby (all of these were not going to happen). I basically had a panic attack on shrooms and now I'm not sure about them. I can take more in a controlled environment, but some part of me feels paranoid I'll develop psychotic or schizophrenic behavior. I'm 19m with no family history, just Alzheimer's and BPD on one side, but I can't help but to feel concerned. I still have a lot of them left, is it a risk?
