I love all the interjections with opinions on whether or not the OP should take an SSRI. That was, of course, not the question, however.
OP, I take an SSRI for anxiety and I make gains constantly. I’ve almost hit a 600 deadlift, I squat in the 500’s, and bench around 350. I’m by no means a poster child for strength, but I’ve done all of this while cutting weight and taking an SSRI. Yes, it will have some sexual repercussions, but the benefits will outweigh the negatives if administered correctly. My only advice to you is this: Take a good pre-workout supplement like Spike or Surge WOF, but preferably both. You won’t be lethargic in the gym. Hell, I’m at 185 now, and I got my biggest (215) while on the SSRI.
Get your life on track first. You don’t become more successful in life because you didn’t ask for or accept help. You become successful by listening to the right people and taking the help when you can get it. Good luck, man.
