If you keep eating healthy and exercising, it seems unlikely that an SSRI antidepressant would cause you to gain weight. You could keep taking the SAM-e with it as well.

It's very likely that an SSRI would cause sexual dysfunction and insomnia, though. If neither is very bad, it's tolerable. I like to use a supplement with 5-HTP, L-theanine, & melatonin for sleep rather than trazodone or Ambien.

If you want to stick with supplements, L-theanine might be helpful.

I hate that it's cheaper to treat depression with prescription medication than to use supplements and alternative methods.

Some other non-drug things that might help you are yoga classes and massage. I know that neither of those are cheap.

Really, any activity that you really enjoy and that gives you "feel good" vibes is helpful. (I guess that's common sense, but I know that when I'm depressed, I often will stop doing things.)

I take antidepressants myself. I have fibromyalgia and need one for pain relief. I need it for depression, too, but I feel like I'm kind of stuck taking it because of the fibro pain.

Have you looked into books that suggest diet and supplements especially for supporting a healthy mood?

I'm rambling because I know that if I didn't take an antidepressant and I was healthy enough to exercise a lot, I'd want to investigate every avenue I could find before taking a prescription antidepressant. I'm not saying that they don't help. It's just that every one I've ever taken has given me some other problem like insomnia or anxiety and I then needed a med to treat that. Not everyone does.

I would just say that if you do decide to try a prescription antidepressant again, keep an eye out for food cravings. I have never gained weight from one without being aware that I was having food cravings - for sugar, for carbs, sometimes just for lots more food than I would normally want.
