Hello, hiker. I can relate to this post!

The same thing happened to me when I was in the beginning stages of major depression. The course your experience has followed is very similar to mine, with a few minor differences.

I would urge you to think about perhaps trying another therapist. When we no longer enjoy pastimes as we once did, it's known as anhedonia. It is a telltale sign of something deeper going on. It should also be a huge red flag to any trained counselor or therapist!

I lost the ability to enjoy an awful lot of music (and I have very eclectic and far-ranging tastes, depending on my music requirements at the moment)---along with the motivation to do any serious artwork or even sketching out ideas (something I had done habitually and almost constantly since I was in my early teens. You never caught me without a pen/pencil and paper nearby!).

This was distressing and worrisome, but because I had no one to ask about it, and these were the pre-internet days, I chalked it all up to the stress of a big, big breakup in my personal life, and other medical considerations, with which I was having mild, but new-to-me, experiences (I was in my early 30's.).

I wondered if it could be depression, but with no one to ask, and the relative wellness I felt at other times, I basically carried on as normal. (I had always been very outdoors-y, was a slim, trim healthy eater, and stayed pretty active. I walked or bicycled everywhere. I'd never had trouble sleeping. I was at my physical peak when these things began---something else I was not aware could happen to anyone. (I had always assumed, mistakenly, depression had to have something to do with lifestyle, somehow.)

HOW I WISH I had encountered someone who knew a bit more about these things than I did! I might have started medications sooner, which experts know can result in a faster and more thorough recovery.

I do not go around advocating the medicated route for everyone. But it was something I resisted doing for far too long. The stigma was overwhelming for me---there were big expectations placed on my shoulders, and admitting to close relatives that I was enduring these kinds of problems worried me a great deal.

I can't tell you how to proceed. That will be up to you. As long as you know you're not the only one, and that this experience really ISN'T all that unusual,
then I've succeeded.

By the way, after 12+ years of medical and cognitive treatment, I actually have gotten the enjoyment of certain activities back that once had abandoned me. It's a relief to be able to say that!!! It might happen quicker for you, and I really hope it is!!

I just hope you find qualified medical professionals that can find the right course for you.
