Different meds can have different effects on different people
I tried half a dozen different meds before I got a different diagnosis and prescription
Each one came with its own unique set of side effects (like 1 anti anxiety drug that gave me panic attacks). Sometimes you've got to try a bunch before you get the one that works for you
Getting any degree at University is the same way, bachelor's is the first level that requires an actual internship in order to go anywhere, it is gone to the point where internship listings are starting to put in their job listing "prior internship experience preferred"
So like the job that is meant to give you the skills to start out is wanting an additional internship prior to being hired. This country is going to hell lmao
