Wow, this is exactly what has happened to me in the last four years. I had some outside issues and started on the depression medication and wham, here I am. I stopped taking all of the meds in early January and am trying to get me life back together, it just seemed like I didn't want to do anything. I haven't been out dressed in several years and still make excuses to get out of commitments to go out. My wife keeps trying to get me to do a girl night or something and I find a reason why I shouldn't.
I'll have to make more of an effort to get out.
