Is there nothing you enjoy? Pass times or hobbies? I feel your situation very much but I still enjoy things, things that keep me ticking over till my day comes. Whatever it may be you should go for it, make your time here as enjoyable as possible & make the most of it.
It's never too late to develop a new hobby as well, something niche that you may not have expected to like. They say the best moments in life are unexpected.
I envy you, that you still enjoy things. Truly, I do.
The op may be suffering from severe anhedonia & apathy....possibly anxiety/agoraphobia...perhaps exhaustion due to insomnia(?)
If so, I can relate to having MANY, MANY interests in the past but nothing now and just stuck in this apartment. Everything is blah.
Anytime I must go out (shopping, work) a panic attack is sure to precede it.
So,...kinda makes it tough to pursue a hobby...
As an aside, (and just so I can needlessly complain a bit more) I just sifted through every country in the world with regards to easy travel (i.e.: visa on arrival or no visa required)....and there are LOADS.
I could practically go to any region on earth but....nothing. I mean not one country filled me with any thought or feeling beyond disdain and compulsive thoughts of discomfort. I've felt like this before but this time it is an entirely new (low) level.
Anyways and on the other hand...if the Op is able to get out and about with relative ease, I'm with you and would also recommend any activities/hobbies to help make the time pass.
