Taking LSD for exam anxiety relief? (18)

For some background, I am 18 years old, have taken LSD 9 times and my last dose was a bad trip in April. I've started getting really bad anxiety pertaining to my exams which stops me working and studying. This is very irritating, as I'd quite like to get things done. I've seen that taking acid has helped a lot of people with their anxiety, but I'm wondering if the immediate stress about these exams determining if I'll get to university, my previous 9 trips, one being bad, and my current kind of crippling anxiety will lead to me having a bad trip and just making everything worse? Thanks
