You have described your condition in great detail.
You mention of "anhedonia", which is a symptom of depression
. However, what you have described as anhedonia is actually depersonalisation. You do not feel emotions in a situation, things seem to be passing by and you are not feeling in grip / awareness of things, Everything seems surreal. Have I got you right?
If you have not got depressed mood or anxiety or you have not had any psychosis
in the past; I suggest you can let the symptoms be. Do not try to medicate them - as you find medications are not working.
Try to have methods to relax, such as yoga, meditation
, music and practice mindfulness techniques. You can also see which situations make these feeling of anhedonia worse and try and make conscious efforts to be "mindful" in such situations. Depersonalisation disorder
is quite prevalent, although they are not commonly seen in clinical settings. People do not walk to the psychiatrist
with these symptoms very often.
It is important to get an EEG and/or CT scan done to rule out a neurological disease especially if you have had a significant head injury
in the past leading to loss of consciousness
, or if you have had epileptic seizures in the past.
