Feeling lost

Recently had my stage 2 breast cancer diagnosis, had operation last Friday.. Awaiting results to see if it’s spread to my lymths, I’m so worried about work and money. I’m divorced, so totally reliant on my wage. Any advice on help I can get, only been in the job 3 day when I got diagnosed. Talk about bad luck. Just don’t need bad news on weds, my appointment for results! It’s hard to stay positive, I keep crying for no apparent reason.... my grown up children and friends and family are being fantastic, but it’s hard to explain how I feel when I don’t know myself?
