What are the best natural remedies for severe depression?

I’ve had severe depression since dealing with a major trauma in my life last year. I tried Wellbutrin but I had such a horrible reaction to it I weaned myself off it after 4 months. I don’t really want any medications. I’d like to maybe try things like accunpuncture or St. John’s Wort.

Unfortunately going to therapy isn’t really an option because my family’s finances were hit hard due to everything. I would really, really like to but even with insurance it’s super expensive (0 a session is what we were told)
I’m only 17 so drinking isn’t an option. I want healthy solutions. I do exercise a lot already (I was a gymnast for 10 yrs) but it hasn’t helped that much.
