Life just keeps knocking me down. I’m exhausted and don’t know what to do anymore.

I don’t usually post things like this, but I just need to get this off my chest.
I’ve been struggling with severe anxiety since I was in high school. It made getting through school incredibly difficult because my symptoms often make me feel physically sick and nauseous.
After school, I became a prison guard. About three years into the job, I developed inguinal hernias on both sides and had to stop working to recover. It took about a year before I was finally able to get back on my feet.
I then started working at a hospital, hoping things were finally looking up. Unfortunately, about a year into that job, my anxiety became so severe that I couldn’t even make it to work anymore. I’ve now been out of work for a year and five months.
The first medication I tried didn’t help, and in some ways made things worse. I’m currently waiting until August to see a new doctor, hoping they’ll be able to help me find a better treatment.
To make things even harder, because I became unable to work again before reaching the required number of working days after recovering from my hernias, I don’t qualify for financial medical support from the state. It feels incredibly unfair that after fighting my way back once, I fell ill again too soon and now I’m left with almost nothing.
As if that wasn’t enough, I’ve lost almost all of my friends over the past few years. Thankfully, my mom recovered from cancer, and I’m incredibly grateful for that. But recently my best friend—the only close friend I had left—died from an overdose.
Right now, it honestly feels like life just keeps knocking me down every time I try to get back up. I’m trying to keep my head above water, but it’s becoming harder and harder.
I’m not really looking for pity. I just needed somewhere to vent because I feel like I’ve been carrying this alone for a long time. If anyone has gone through something similar, I’d really appreciate hearing how you managed to keep going.
