I've been on and off different meds for years. It's possible that taking a reasonable dose of test (especially a long ester to minimize fast highs and lows) can improve your moods. There was another thread on this a few days ago from a guy who experimented with low-dose of prop.
Personally, accutane and B5 are the best things for acne. At least for me. 10 grams of B5 ED in divided doses, along with 40-80mg of accutane before bed (to minimize potential mood swings or initial side effects) will achieve miracles with skin quality. You said accutane is out but didn't say why. Hassle to get but the sides you have/will see from anti-depressants are a LOT worse than anything a controlled dose of accutane will give you. Personal bias though.
To put it simply, I think test might help your medical situation by compensating for areas that are lacking (appetite, mood, self-confidence, libido, etc.). SSRIs supressed my hormone levels a bit (had them checked) and made me store more fat. My $0.02.
