Am I being emotionally abused by someone with cancer whom I care for?

Someone i know was diagnosed with cancer couple months ago. she is a sweet lady and i have been taking her to the doctor. well since she was diagnosed she started to change like being snappy at me and especially demanding. i don’t get paid at all i do it from my heart. she does not talk to other think she is trying to change who i am because of her insecurities growing up
and putting it towards me. i know its a stressful time but i don’t appreciate the over criticism and shutting me out. i love her but if it continues i will have to withdraw being her caretaker. seems like every time lately my family try to help someone we get burned. seems like the world is getting meaner they don’t know what help is anymore.
