May be bad timing but genuinelly, keep trying. Yeah I made a post here, but before this I was genuinelly struggling. I was unemployed my first 4 months out of college, then worked a ****ty food service job for 6 months, and then worked a low paying job where I was struggling to make ends meet with bill payments. I was depressed as a mf, the first 10 months of last year may have been the absolute lowest I have ever been in my entire life. No motivation to better myself, no friends to talk to, no space of my own to relax.
Now I'm telling you this because I wanna say that this **** is tough, this wasn't handed to me easy peasy. It took numerous therapy sessions and lots of reflection and changes for me to get to where I'm at now. 4 weeks ago, I was legit crying in my car because I got rejected for the umpteenth time, it got that bad. But still, no matter how bad life punches at ya, keep striking back. It can't dodge all your punches.
Now as for you specifically, I know you have experience pet sitting and walking animals, so for the time being, I would check out some pet-sitting apps such as Rover. And also, if you want to work at a petsmart or something like you said you did, put the pet sitting stuff on your resume if you haven't already.
