Note: Question/issue explanation starts with bolded word.

First off, I have been having sleep issues since August 2012 which has basically halted my life, not so much due to not being able to fix it, but due to:

A. Not realizing the problem actually was sleep until last year in May
B. and then only having two months of better sleep before frequent sightseeing and whatnot on family's part completely delaying me fixing, replace that with working to move back to my home country and then fixing the home itself and you have the other reasons which delayed it...I will end the backstory here, sorry for the wall of text >_>;

Aside from emotional issues and from what I've noticed OCD-like symptoms alongside others due to said sleep issues, I have another which I can't find an explanation for.

I have an extremely hard time watching or reading, or playing things I have missed out on in this period.
For example, Doctor Who. I had a hard time convincing myself to watch this(Season 7) which I did eventually accomplish, but it was ridiculous, this is the show I consider to be my personal favorite by far, more than that, I find it extremely positive and it often gets me motivated and my creative cogs running.
Other things as well, just attempting to do so will literally make my shoulders slump and render me close to tears, caught up in sheer anxiety and thoughts about how much I have missed and what not.
It's really pissing me off, it's just wasting more time and the issue doesn't crop up with things that are older than I am, meaning it's restricted to things missed out on when sleep deprived.

Is there an explanation for what I am experiencing at all? Just having a word to place on this would help a lot.

EDIT: Hopefully this is in the right forum, if not, please move to the appropriate location :3
