Work tomorrow:(

Okay so I've had almost 7 weeks off work in total (not all by choice) as I was on holiday for 12 days, then came back to work for around 2 weeks before I was signed off after my laparoscopy. The doctors just kept signing me off work with pregnancy related symptoms and it's my first shift back tomorrow. I'm working with a lady who makes me feel generally uncomfortable as she's a senior and I'm new to my job, I don't think she means to make me feel like this I think it's more of the fact she knows a lot more than I do. I suffer with anxiety and depression which was real bad at one point but starting my new job made things a bit easier regarding my mental health! I'm a carer in the community and the clients I'm working with tomorrow are ones I've never met before so that's another stress. I'm genuinely terrified to go back and I don't think I'm ready. I've had a lot of stress these last 5 weeks after suffering a miscarriage and though work is probably the best place for me to be I'm so so scared! I've somehow manage to convince myself that if I leave the house I'm going to die or something really bad is going to happen to me and I'm just generally finding this really hard. Can anyone help me at all😪
