I would not do prescription drugs (only after honestly trying everything else.)

Supplement magnesium (so key to health and so neglected). Try it, you won't regret it, unless you have some psychological barrier to supplementation.

Supplement gelatin before sleep (which contains a lot of glycine, there are studies showing it regulates serotonin and dopamine. In my family's experience it is amazing for helping you sleep. Also it is the reason why in my country broth's are seen as relaxing before sleep: they contain lots of glycine)

Look into lifting weights, I took it up after being depressed for months after my last breakup and it has been life changing. It has so many benefits from increased metabolism, growth hormone, testosterone.

Spend time in the sun frequently

Do something that makes you afraid/thrill. For example, I took motorcycle riding this year, hard to be depressed when your heart rate goes up. It might seem temporary but it sets the beginning for change.
