Am I overreacting or being selfish?

Hello,

This is my second post and I’m still learning the ropes and getting used to reaching out.

My mum was diagnosed with stage 2 breast cancer and is being monitored and is doing as well as she can with some struggles with her good and bad days. 

I am her carer and I live with her, Although I probably would have moved back in when she first diagnosed to support her the best I can.

i’m just wondering if I am overreacting as I have noticed since my mum’s diagnosed a lot of friends haven’t been in touch or even asked if we are ok. 

im generally a person who will always have time for friends and is usually on the phone to a friend for 2 hours some evening’s listening to their problems.

since the lockdown I have been reflecting on the fact I’m always there for my friends even though I was working a 40 hr week, travelled 45 minutes each way to work, became a carer and still wanted to do things like go to the gym.

I have been noticing since my mum’s cancer people are still still expecting me to be on the phone for 2 hours knowing my life had become busier and when they do call me and I confide about how I’m feeling there is no sympathy or understanding that my life has changed and I have neglected a lot of things I used to enjoy.

i want to be there for my friends but it’s hard to talk to certain friends as they make you feel like you are moaning and I’m told the classic “you have your mum” and yes I have my mum but my mum has cancer and it’s the future can be uncertain. 

Am I overreacting? Being selfish?
