I have fixed my diet, my sleep schedule and I work out regularly and all of those help.
But still, I sometimes wake up and my mind betray me. I have no reason to feel sad, but I do. Is there more I can do to fix it?
I have upped my protein intake and started eating more meat to get higher quality proteins, because apparently low protein is linked with depression.
I also stopped porn, because it's unhealthy. My libido is still pretty high which I think is good, right? High T? Or not? I cannot check my T levels because healthcare in Germany is shit. But I am still doing anything to naturally maintain high T.

I say mood swings because sometimes I am also euphoric, not always depressed. And it's chronic. Had it for like 12 years by now.

Anything else I can do?
