I'm lost....

I'm aimless, I wake up to exist with no real purpose. I go to work to come home and waste time till the next day. I have spoken to alot of people about this problem but I guess the easy way to put it is I've been burned alot. Kinda programming me to expect the worst, so I'm afraid to take a risk/improve so i don't do anything but know I have to and im stuck in a endless cycle of self loathing and regret. Anyone have any input or advice about how to approach/ deal with a mindset like this
