You have had a great deal of sadness over the last six months. You are grieving for your grandparents, as well as trying to adjust to the shock of your mum's diagnosis. All this - and working in a job where you are caring for people who are unwell/infirm at home. There is no wonder that you're feeling anxious, and low in mood.
Friends sometimes don't know what to say, when someone has things going on in their lives which is beyond their experience. It may not be intentional - sometimes when we're feeling very low, friends aren't sure how to respond. It can feel very hurtful though. It may be that you have to make the first move - maybe to a friend you're particularly close to normally.
Your mum might like to talk to you about what is going on, but may be waiting till you're ready to open up? Any upset she may be feeling, is likely to be at the cancer, and the loss of her mum...and not with you. Sometimes it's hard to be open about how we feel...trying to protect the person we love...but you may find you and she are feeling the same sort of emotions...
The thoughts you have about the fear of losing your mum the same way as she lost hers, is natural. The future suddenly feels an unknown landscape, and it can feel scary.
I'm wondering if you could discuss with work whether you could have a week off, when your mum starts her treatment, to help support her? This way, you can be there for her, whilst you all see how the treatments affect your mum. Alternatively, with all the stress going on, sometimes people are signed off sick by their GP, for a couple of weeks or so, to help ease the pressure. Your GP may also be able to arrange for some counselling for you. To find out more about what support is available in your area, click here.
