For reference I’m 28m. 

In late 2019/ early 2020 my sister was diagnosed with schizoaffective disorder. Apparently my grandma had 2 sisters who also had some type of schizophrenia.

I started smoking weed during my sophomore year of college (2014/2015) and over time it became a daily habit. I’ve been trying to kick the habit but honestly it’s been a struggle to stop completely. I’ve decided to quit again and I’m doing my best to abstain forever. I also used LSD and shrooms in college. 

I have a huge anxiety about waking up one day with voices in my head, delusional, paranoid etc.

Has anyone had a similar history? I know the chances of developing schizo are about 10% if you have a sibling with it, but the chances go up with the drug history I have… if I could go back I would never touch any of these substances
