Libido and sexual frustration

About 6 months ago, my sexual activity diminished abruptly. I'm a 49 year old male. I don't have a sex partner and never have, so that's not a factor in the change. I was thinking hormones... HOWEVER ... I just thought of a new clue. I am sexually frustrated a lot due to my diminished sexual activity. I feel really horny sometimes, but I also feel indifferent and spacy. Instead of looking forward to sexual activity, it seems like total drudgery to me. Wouldn't that mean that my hormones are still present? Therefore this abrupt change resulted from psychological changes?

The last few weeks I have noticed a decline in other areas of my life. I used to diligently exercise and stretch every day to try to fight depression and back pain. Now I just drag myself out of bed and I often don't bathe or shave before going to work. In fact, I sometimes wear the same clothes and sleep in them and then wear them again. I am self-employed, so nobody can criticize me (openly LOL). I can tell I am really close to falling apart. Something is going to happen, because I have nothing left to give and what I am giving isn't good enough anymore. Hopefully it will turn around soon somehow.

sounds like depression setting in ...
