Am I a bad person for this?

I am a CNA night shift on a medical surgical floor, it is stressful. I worked in nursing homes and this new hospital job is so stressful. I have made mistakes and I am not sure how I didn't lose my job. It was a minor mistake, due to lack of orientation, they threw me right in only having 4 days of orientation. I am new to the hospital setting, caught on fast due to prior experience. I would say I am good worker, I don't sit around I do my fair share. Anyways, I called in 7 times being there 3 months. I had migraines, and had stomach issues like 4 days I called in. I found a replacement for 2 of those days I didn't feel right. I am afraid I am going to lose my job, I do have severe depression and anxiety, but I don't want to make this a "woe is me" this job is very demanding. I love helping others, but I don't know if the hospital is for me? It's really stupid, i worked hard to get this job and it's like I am taking it for granted? I am 26, still living at home. I hope by in the next few years I am on my own, I want to save up money. Get a car eventually. It's hard now a days. I feel so stressed right now.. there is NURSES my age there that know what they are doing. I am 26, being bossed around by a 23 year old nurse
