Sorry to hear that, I know what it feels (or doesn't feel) like.

Feel free to ignore my advice but doing the following helped me get out of a bad place:

How do you interact with natural light?

• Do you wake up and watch the sunrise? If not, try that. Look right into the sun (or otherwise the clouds) and around
• Do you spend too many hours looking at screens? Try to reduce that and if not possible, use the night shift or similar function to turn the tint more orange. You can use a red light at night time
• During the day do you look at enough green foliage? Try to do some grounding or work out barefoot in some park
• Do you get enough UV from the sun on your skin at around noon? At least 15 minutes

I would force myself to do all this no matter how I feel, could try for a month; discipline is crucial.
