Seeking Advice for Physical Symptoms and Depression/Anxiety

Hey so I'm new here, I will just summarize what I have problems with. I've had severe depression/ anxiety since 2017 and have needed medications, though, I always feel like it may be a physical problem as most of what I feel is only felt physically (very low mood, off-put etc.), I also suffer from back muscle pain, and also noticed this doesn't help my poor mood. I also, always feel pretty tired unless I get caffeine, as well as I feel like I get tired to easily when I exercise.. I've done a lot of blood work, but according to my diagnosis, my thyroid appears to be fine, as well as the majority of my blood work.. I am also taking Vitamin D, (my blood test concluded I'm well above the amount of vitamin D people have), as well as I'm still on testosterone treatment for low-T Really, any and all hell is appreciated. A summary of this is that I really feel like something is physically off, or something just isn't right physically with me, causing my symptoms. Thank you!
