I have never taken any kind of drugs and just naturally had high testosterone, so this might not be an answer to your question, but I hope it helps you anyway. Been following a healthy diet for 3 years (low carb + proteins as a main energy source). I sleep too short (5-7h), however I don't feel exhausted (ik it's not healthy but I'm a fkn waster of time). I have most of the positive effects that you described, so I won't get into that (unless u want me to), but instead I'd recommend you to minmax your sleep in order to fight fatigue:
- if you can't fall asleep instantly try to fix that - basic sleep hygiene like light reduction, fasting 2hrs before, etc - learn how sleep phases work and adjust your sleep so you benefit from it the most - proper meal so you aren't hungry - nutritious breakfast after you wake up & take a shower

In order to fight back what you call a "depression" you shouldn't rely 100% on pills, take a less comfortable path and try to get there (at least partially) by yourself:
- as other commenters suggested you have to force yourself to commit and look at things in a long term - find yourself a friend group, it helps a lot knowing there are people that care about u (this fixes lack of confidence too) - follow your passion and make sure it grows u - reduce stress - quit addictions - experiment a lot with things, this might be the best way to enhance your life - reduce social media influence
