I'm getting tired of it all

Okay, so I've been in my new area for about four months now. I'm getting tired of doing the same old thing over and am over. I know it's my burnout surfacing. I'm trying to put myself back to school, but I need the funding to do it ( I am going for a certification in the medical field. ) Yesterday, I found out that there was a miscommunication issue and I was suppose to show up on Monday. But due to the lady getting COVID, it wouldn't have mattered if I showed up on Monday because I would have gotten the same answer that I did yesterday. That answer was that they would call me within the week to reschedule. I said it to the director who was talking to me, that even if I don't get approved for the funding. I'll still go for the certification. Between my anxiety acting up now, a long with my depression. Its making my day stressful. There are times where I just want to throw in the towel and apply for disability, and just be done with it all.
