I kind of know where you are coming from, I have a bad case of anhedonia...it's a very strong feeling of "no interest" too...some medication I've been taking recently seems to help some, so if you're not taking any, that might be a possibility for you?...I know I won't get better without meds, that's for sure....in the meantime, I watch a lot of television...it helps me to forget about my surroundings until I can get my meds straight. Antipsychotics seem to help me more than antidepressants so keep that in mind if you decide to use medicine to help you out. I hope you can find something soon as the type of feelings you are having are dangerous.
