Did I make the right choice?

Recently, I quit my job to focus on my career. I have been working non stop for 3 years doing general and hard labor work. I would quit one and start a new job the next day to make money for bills. After some time, I decided I have to take the initiative and start working on my career goal or else my college degree would’ve been pointless. But even after quitting, things aren’t going the way I thought or imagined it to go like. My savings was only enough for me to pay off all my bills for about 2 months, working at door dash was my alternative but because there has been an increase of dashers around my area, I barely about to secure 2-3 hours of delivery time a day. I would literally only make enough to cover 1-2 bills a week and fill my gas up once a week. I thought I was ready, but now I’m feeling doubt. My anxiety is starting to kick in again. Not to mention today I received some bad news about my grandma too. So I’m in a rollercoaster. I felt so happy and eager to leave my job and get some time to focus on my works but instead all I’ve been doing is trying to find ways to pay bills again. I thought about just repoing my car and avoid making car payments to save some money but then I won’t have a car to dash. Things always gets too complicated around me. I feel like I have no motivation to continue my career nor do I have any motive to do anything anymore.
