Anything that you put into your body that is mind altering can be very harful..
I know this from experience.. I used to be a very heavy drug addict about 5 years ago.. i am only 21 btw and 3 years ago out of wo where smoked some spice that a friend wanted me to try and boom first panic attack that left me with now a full panic and anxiety disorder.. I am terrified almost all the time.. some days are beter than others but... once you have a scary experience like what you have described it is really hard to get it out of thought... good news is that it will eventually pass although it does take time and therapy for alot of people.. I would recomend meds until you try intense therapy only because sometimes meds can make a problem like that worse.. and no one wants that,
hope that helped you!
Sounds scary, maybe therapy forshure will help... Don't do drugs.. Is bad really bad....
Yes you should get some counseling.. my advice is to not do any drugs anymore. Also, if you r scared of being in the dark keep a small night light on.. I used to get anxiety about the dark too and saw ghosts a lot and sleeping with night light helped me feel better and I didn't see them anymore. Have you talked to any of your family about your depression and cutting? You should and get some help too.. you're not alone
