I feel it sometimes - but you just turn an hourglass upside down and the sand keeps spilling.
Try not to obsess on whatever negatives you have.
Share them a little more - after all, what your saying is you feel like your life is in a mess and going nowhere - no?
If your car broke down - would you just scrap it or maybe just fix the problem that made it break down?
Your tired of the way your life is - not tired of life. Life has too much to offer for you to be tired by it - its finding the 'right' things to do and people to be with and feeling peace of mind.
Life can be amazing.
It can also be not so amazing.
All I know is that life rarely knocks on my door - I have to go out looking for it for it to get interesting enough to stop me wanting to just go to the desert with a bottle of something and a bag of assorted potions and exotic things.
Not that England has that many deserts.
OK - head to the hills!
Hope some of this helps.
I do sympathise with how you feel and empathise, which means I KNOW what you mean 100%.
I think its best to be stay alive and see what happens
Or make things happen.
Sometimes they just happen!!!
