No, just the opposite actually.
i follow a skin care routine involving skin cleanser, toner, moisturizer, exfoliater, and vitamin e oil. It's made a big difference, my skin glows more than it ever has. If I didn't have such bad social anxiety I'd also go to a beauty parlor to get facials and go to a dentist to get my teeth whitened.
i also have a couple of hair products that I use, blow dry my hair too.
i could exercise more but I still exercise occasionall. i brush and floss my teeth everyday.
As for my wardrobe I regularly wear button up shirt tucked into slim fitting jeans with matching colored leather shoes and belt. Always make sure that my clothes are clean.
i also have a ton of different body washes with various scents cause I like to smell good. My favorite is this coconut and coffee body was, omg it smells so good.
Ironically the more depressed/suicidal I get the more I care about my appearance. I think it's a reflection of the fact that I've noticed as I go deeper into depression I'm more empathetic towards myself. I have this growing attitdue that if everyone dislikes me, no one loves me, and no one ever will because I'm so unloveable then the only person left to love me and care about me is myself. So I should I take care of myself and dress nicely for myself so I feel good about myself and I feel like someone actually cares about me even if it's only myself who cares or even notices how much work I put into my appearance.
slowly my depression is turning me into a metrosexual whereas just a year or 2 ago I was a typical nerdy guy who put little to any work in his appearance.
