Do you have any idea what this could be?

You ahve probably been traumatised, possibly as part of Mind Kontrolle on somebody's part, and it is the nature of such things that the victim cannot remember it: I mean, it wouldn't be any good if the victim COULD remember it, right? At least you are able to reach out for help. Yes, probably some Mental Helath counselling WOULD be a step in the right direction, though you probably won't remember enough for them to do a lot about the CAUSE until you are perhaps in your early thirties, you can begin to rebuild your psychological strength with their help. Hopefully they won't just put you on pills, which is how a lot of them operate nowadays, as the pharmaceutical companies tend to "control" the docs these days...as people of your age sometimes get more depressed from the pills, actually. But, if you are actively working to feel better, that is a step in the right direction. Read, "Trance-Formation of America" if you can, to learn about others who get that BLANK feeling because their minds were traumatised previously. You probably won't believe this, but it is often a parent--frequently a father--who was brainwashing and/or molesting the victim, yes, even a boy! But, if you HAVE been Mind Kontrolled, you will probably deny this vehemently. Avoid alcohol and sugar and try to get lots of healthy exercise and rest. Eventually you should begin to heal anyway, if you just "hang in there" but some mental health counselling can really speed that up.
