Cancellation charge even during Covid

I took out a contract last year with planet fitness with every last year december. Dur to the fact that i was travelling i froze my contract to have it reatarted in june. When covid started Planet Fitness then haulted debit orders from about April, which is appreciated. However i have a parent with co- morbidities and so i cannot risk going to gym and putting my mums health in jeopardy. I requested to cancel the membership only due to the pandemic however they still want to charge me a cancellation fee. I mentioned under normally circumstances i would totally understand the cancellation fee. But we are not under normal circumstances. Further more who would be responsibles for medical if anything had to happen to my mum because of my ignorance. At the end of the day this is my choice as to whether to go to gym or not and not i feel forced to. Also due to my work i am unemployed and so i need to redirect my finances to more priority needs. This is totally unacceptable and u fair that even in a pandemic these business still want to enforce normal rules and regulations. Very u helpful and will never use or recommend planet fitness ever again.
