Your list is EXCELLENT! If you want to try those first before taking meds, then do it. Sometimes we're in such a funk for so long that we think the answer comes out from a bottle. I was that way and decided to try the positive changes first before asking for a prescription. I'm glad I waited because I'm much happier, naturally.
The exercise especially is great at inducing pleasure endorphins into your body. All of your goals are great in terms of achieving the new you!
