I really do not mean to sound like an ass, but if this is even a roughly accurate description of symptoms:

Please.

Ideally once a day, but at minimum 3 times a week:

Go for a 20 minute walk, outside.

Either dusk or dawn probably have the most mild weather.

I have been chronically depressed before.

This will not 100% guarantee fix it, not by any means, but it does help with a lot of the physical symptoms here described.

The difference between basically 0 physical activity and a light amount of regular physical activity is actually substantial.

Bring headphones and sunglasses or w/e if you need them.

Get a hat or a beanie or something if you don't wanna do your hair.

...

Also, if you are regularly consuming ibuprofen... you know that too much of that shit fucks up your liver, right?

If you're looking for mild to moderate pain relief, I would suggest instead CBD, if you can get it.

...

Also... set a phone timer or physical kitchen timer to go off every 2 hours and drink a cup of water, maybe make some tea.

Establishing some kind of basic routine, a structured schedule for your day, even if its just a few things, even if you miss some things some time...

It can help.

...

Also, possibly consider a HappyLamp if you suffer from SAD (Seasonal Affective Disorder, great acronym, right?)

These are ... not too expensive lamps that use bulbs that come far closer to hitting the full spectral range of the sun than most normal bulbs.

Basically, turn it on for 30 or 45 minutes in the morning, don't stare at it, but just let it light the room, do your wakeup routine with it.

This can help with SAD, and renormalizing your circadiam rhythm (sleep schedule).

Again, not guaranteed to magically fix all your problems, but it can help, especially if the weather is very overcast for a long time.
