Just got laid off, now what?

I'm about to be starting a new job, but I'm worried about my ability to fulfill my duties. last times I've worked it's been tough to push the entire day and I'm scared for this job.

So I lost my job after being hospitalized for severe depression and anxiety. I have not been unemployed since I was 18 and it has taken a big toll on my mental health. After almost two months I found what I thought was the perfect job but I wasn’t aware that they were going to give me so little hours. I am waiting to hear back from other interviews I did but I’m terrified of having to quit this job because it’s a small business and I see the opportunity to grow with them as they go. How would you handle this situation?

honestly..... I'm stressed out a lot more than I let on. my job has been cutting out the part timers ( like me) and adding more tasks to what we already have to do. I'm disabled so 3 days a week is the maximum I can do without a severe burnout or mental break. I'm also on disability so having less than 25 hours a week scheduled doesn't mess with my current payment because they expected and planned on me being part time with less than 3 days a week. but now there's this constant worry of me losing my job because they keep trying to call me in on my days off to cover for the call offs and now that I'm the only part time person it'll fall on me but like I CAN'T handle it mentally or physically.
