Absolutely. Took me decades to get a decent diagnosis and get halfway decent treatment. But I've found that PDOCs usually just treat symptoms if symptoms are very complex and they avoid putting a name on it. I've had very poor mental energy since an adolescence even though I managed to get a technical degree from college. Mood disorders have a tremendous effect on the part of the brain that regulate mental energy, imho. I get drained extremely quickly from the slightest irritability, agitation, anxiety, etc. and I don't think PDOCs catch on to that very well at all. PDOCs downplay lack of energy and don't take it extremely seriously when it continues for a very long extended period of time, imo.
