I start a new job on Monday after 10 years as a delivery driver

After 4 months I accepted a job as a delivery driver. I have read a lot of threads here and could not find my exact situation. It is not my dream role, but the pay is fair and the people are kind. What helped you in the first month?

Thanks for writing this out. I went through something close to it 4 months ago, and it settled down once I kept a simple log of every call and form.
