Dropping LSD for the first time - am I too young?

Hi, I'm looking into trying LSD for the first time, but I have a few concerns and I'm hoping to get advice from some more experienced users.

I'm a 15 year old high school student and I'm very interested in experimenting with psychedelics. I'm a daily marijuana user and I've been smoking weed since the age of 13. I have also eaten Psilocybin mushrooms 4-5 times and I find them to be quite mild for the experience I'm looking for. I'm very aware of all the pros, cons, side effects, and dangers of these two drugs. I am usually easily able to control my emotional state and stay in control with both substances and lately I've been in a very spiritual and positive state of mind, so I'm confident that I would be able to stay calm if I were to start having negative thoughts or a bad trip/panic attack.

However, I'm genetically prone to schizophrenia/psychosis and I'm a bit worried about having an LSD induced break from reality. I also wonder if my age would have any correlation to that. Does anyone know what the chances are of a worst-case scenario occuring?

I'm planning on buying a 100ug tab - would this be a good amount for a beginner? I'm 5'2 f 115lbs.

Also, any tips or advice? Thanks so much:))
