Severe depression and anxiety

Alright ladies I need opinions. I work at a decent place I care for adults with mental/physical disabilities. I honestly love my job and the clients I work with. I have a pretty easy shift 12am-8am my only duties are to clean the clients house and check on them every 30 mins through the night. I was diagnosed with severe depression and anxiety last year but struggled with it for 11 years. After some time it was mostly managed with medication and I was lucky at the time to be a stay at home mom/wife. But some things happened and the husband and I split for a couple months and I moved to a new town and had to work to support my daughter and after a couple months of working my depression and anxiety got really bad again so bad that I was thinking of ways to take my own life ect... I've missed a lot of work over it (I've now been at my job little over 5 months) my husband and I are back together and he is now only working part time. I'm on new medication but it isnt working so I have a dr appointment in the future to figure out my next option. I find myself crying and have major anxiety attacks every night before I leave for work. I'm honestly wanting to quit my job. I have had to work with clients that are known to threaten and attack staff and not feel safe. I've worked 16 hour days back to back and come home to sleep then right back to work and it's a lot for me. Am I crazy if i quit my job? I feel like i am never home and i never get to see my daughter. I need advice bad! Please help
