*shrug* It's your life. If you think you want to graduate before looking for a job that's your decision to make. But that doesn't make your environment any healthier, just gives you a reason you might want to stick with it longer.
I'm not sure what you really want though. You say you want chemical castration drugs, but you don't want to get them without a medical prescription*, you don't want your parents to find out, and you don't want to fight their flagrant privacy invasion. As far as I can tell these three conditions are not simultaneously satisfiable.
*well, specifically you said "I don’t want to break the law" re: using a non-FDA approved medication. Which is a laudable impulse, but getting any sort of chemical castration drug without getting a prescription involves things at least as legally grey as that
