Should I quit my job and take the risk???

My husband and I aren’t struggling for money but we have debts we need to catch Up on. He makes enough to pay our bills and have a bit of spending money but my income definitely helps keeping our minds at ease.

I’ve been very depressed with my job lately and want to find a new one but nothing pays as well. ( I have no experience)

Should I quit Walmart and take a grooming program?

Is it fairly easy to get a job after schooling?

I would work and do the program but I have medical issues I’m dealing with and I don’t want to stress myself out anymore than I already am. Plus Walmart refuses to work with my schedule and constantly over works me. I’m always alone taking care of the whole apparael department along with jewelry and the fitting room. Leaves me no time with my husband. I can’t say anything positive about the job except I made more than my last one. I even get harassed for my religious believes and people are always making fun of me. Please give me some tips and job ideas. Anything helps
