I am sorry to read that you are experiencing this. I have experienced some of the same sort of thing, which made me want to write to you.

My belief is that these kinds of things are physiologically based and can be helped by the right foods and supplements to support your brain health. Exercise can also be helpful.

I think one of the main ways exercise is helpful for mood and brain function is that it gets us to breathe deeply. Breathing exercises or singing can provide much of the same benefit. Yoga, tai chi, or chi gong are often helpful, too.

The part about not responding to music especially caught my eye. I have chronic fatigue syndrome/ME. Right after I got that was the first time I noticed that I didn't want to hear music much anymore. It was a big passion for me before that.

I gradually started wanting to listen to music again sometimes, but have never gone back to listening to it every single minute of the day, if possible.

That's not to say that the same thing will happen to you.

I have experienced the lack of interest in music as more of a lack of the energy to pay attention. Listening to people talk also seems to require a lot of energy and leaves me exhausted, so I limit how much I do it.

I tried to find a site that I bookmarked a couple of years ago. They specialize in nutritional supplements for people who are stopping psych medication. I couldn't find the bookmark, though.

I would suggest doing some web searches for "brain nutrition", especially for foods and supplements to help people with depression and to help with dopamine production.

I do have a couple of links for foods to eat. I have found that walnuts, avocados, salmon, olive oil, oranges, spinach, berries, and Greek yogurt seem to help my mood and brain functioning. Eating some kind of protein with each meal also seems to help me.

Here are the links:

As far as supplements go, omega-3s are very good.

If you do a web search, you can find web sites and books that give suggestions for foods and supplements to help brain health and function and also suggestions specifically for people who have recently stopped psych meds or who want to stop them.

I hope you find a solution. Being in a place where there's very little that you enjoy is very tiring psychologically.
