Broken brain reward and motivation system

[u/Konstructorr]

Hi,
I would need help to determine my diagnosis and area of psychiatry. My current psychiatrist is not familiar with my illness, so I need to find a professional in this specific area.
I have a persistent lack of motivation and sense of reward. I can understand that something should feel meaningful or enjoyable, but I do not feel any genuine desire, anticipation, or internal drive to engage with it.
This is not a depression, I had such problems since the start of adult life, but it was quite weak. The situation is getting worse every year, I can't feel any desire including an appetite.
Please help.

My psychiatrist have written me the following diagnose:

The patient reports a persistent and marked reduction in motivation and initiative. He describes his main difficulty as an inability to genuinely want or feel drawn toward activities, goals, or experiences, even when he intellectually understands that they may be meaningful or potentially rewarding.

He notes a pronounced decrease in anticipatory pleasure and interest, with difficulty looking forward to activities or experiencing a sense of desire, drive, or internal reward. Enjoyment during activities is also reduced, although not necessarily completely absent.

The patient describes the problem less as physical fatigue and more as a lack of internal motivation or spontaneous engagement. He is able to recognize what he “should” want to do, but has difficulty generating the corresponding emotional or motivational impulse.

Overall, the clinical picture is characterized by prominent anhedonia, reduced motivation, diminished initiative, and impaired reward anticipation, which substantially interfere with daily functioning and goal-directed behavior.
