Well, first of all you clearly don't have diet and working out on lockdown. And it sounds like you don't plan on having these in order until you start a cycle. You have no idea how many people say they're going to do get their shit straight as soon as they start a cycle, and then don't. Instead they rely on the gear. This can be disasterous.
Here's the bigger issue though. You don't know how YOU respond to steroids. Some people feel great on them. Some people feel elevated. Others do not. And almost nobody feels good after the cycle is over. This is NOT the solution you should be seeking at this juncture.
My advice: You were once at 10% bf before in your life, naturally. Get there again naturally, and see how you feel. Don't consider steroids again until then.
As a side note, consider getting bloodwork done to make sure nothing is awry that could be contributing to your depression. If you do have a medical condition, you may need to address that. If for whatever reason you decide to do a cycle after reading this advice, YOU MUST GET BLOODWORK FIRST.
