Work - have I made the right choice

Hey all, I'm feeling a little lost and confused at the moment. It's a bit of a long story but I had to leave a job that I loved, that had so much flexibility for health reasons. I found a new job fairly quick in aged care hospitality. At first I found it emotionally hard but then started to love it. I only worked casual afternoon shifts (5-25 hours a week) was always home to get the kids off to school in the mornings, went to after school care some afternoons their dad could get them from school others. But then we got new management, and she was constantly changing the roster, the bitchiness in the place got worse and worse so I decided to look for other work. Again I was lucky enough to find a job fairly quickly. It's in a kitchen environment, part time guarantee 16 hours but current doing 25-30. I was really happy with doing just the 16 hours am struggling with working 5 days a week. My son is in before school care 5 days a week (he copes well) I like knowing I'm gurenteed work and will get holiday pay/sick pay. No public holidays or weekends etc. but I recently lost my dad and I'm feeling physically and emotionally drained, working alone a lot of the time or with one other person I'm finding I'm alone in my thoughts a lot and with the passing of dad and previously suffering depression I'm Finding I'm really feeling down/depressed again. I'm scared I made the wrong decision. I don't know wether to try and stick it out or to start looking for something else. I'm just so confused. My husband is very supportive and always tells me to do what makes me happy. We have struggle financially a bit, but the last 6 months we are getting back on our feet. I'm worried I will be setting us back again if I change jobs again. Casual work is fairly easy to find in my location but part time or permanent jobs are harder to come by..... 😢
