The struggle is real

I've been really struggling mental for about a year now. My moods are so unpredictable!! Work is my issue, I'm a retail manager with an ongoing staffing issue. Every single day it's something & im just burnt out. As of right this is the only income my husband & I have so I feel stuck. I am working on my resume but I really need help mentally until I can switch jobs. My anxiety it at an all time high, I'm always mad and flipping out on someone, I've lost all patience, I cry all the time, I'm so tired physically!! I don't have time or money to see a doctor to be put on anything. This has gotten so bad I honestly now understand why people consider suicide, life just becomes too much. It's like ppl think I'm suspose to be this superhuman and never fall off. Any suggestions on how to get through this real low point?
