37 female and thisclose to quitting it all

I'm about to quit my job because I'm just tired of life. Tired of everything. I don't get paid enough but it's the only thing I have because I left my profession of 12 years because I was so stressed out and couldn't take it anymore. All these jobs suck, no one pays and I feel stuck. This is making my depression worse and I'm like what's the point anymore. Everywhere I go it's same. What is the point the routine? Get up, stress up in traffic, sit for 8 hours, go home (stress in traffic), maybe have 4 hours of free time ( if you're lucky) Repeat. Weekends? Go by in a flash. Can barely afford to live. There's no point to my existence anymore. If someone comes up to me again with a question or a problem, I will scream. Every little thing is getting on my nery. Yes, I have an appointment to get medication today. What good will it do? Just numb the pain so I can stay a clog in this machine? No thx.
