Firstly, go ahead with your training...the nursing home centers and hospitals love male CNA's because of the lifting and transfering of patients. Plus, you'll be able to see if nursing is for you. Also, you'll be able to see other hospital degree programs in action that may even be more suitable for your tastes. You'll find there is more than just nurse or doctor. Respiratory Care (my thing), Radiology, Physical Therapy, Occupational Therapy, Medical Technologists are just a few of the different gigs that make up the healthcare team.
As for drug testing: Employee drug testing is generally limited to drugs of abuse. I know of no screen for SSRI's. Also, any drug you have a perscription for is OK. Just list it on your form. It won't count against you. I dare say that most won't know what it is.
Good Luck in your endeavors, even if it means you won't get to post as much.
