You should always lift weights, with or without T support. A well-designed program will only help every other aspect of your health and fitness. Stopping your training was a phenomenally bad idea.
You’ve lost 8 pounds since your thread in January, so yes, fix your nutrition ASAP. You’re literally malnourished and it’s getting worse week after week.
Basic nutrient deficiencies are the very likely source of the majority of your problems - the low T, the stress/anxiety, the lack of motivation, the training problems, everything. That should’ve been addressed before starting any medications.
Eat like it’s your job, hit the gym a few days a week, get up to 170, then see how you feel.
