welcome to pc! sorry to hear you are having a rough time right now. i think you'll find this community very supportive. sounds like you are doing some proactive actions to deal with your depression and anxiety. is your pdoc aware of the problems you are experiencing? perhaps your meds need tweaking til this episode passes or he may try a new med(s).
the depression can certainly make you feel exhausted. i call it draining my mental energy.
one thing i know helps me often when i'm depressed is a daily regimine of exercise. it releases the "good' chemicals in the brain and helps lift depression. have you tried this?
keep us posted on how you're doing or if you just need to vent, please do. i'm happy to listen.
