I'm sorry to hear about all your troubles. Regarding the MacBook Pro, what happens when you try to power it on? Is there any response from the device? If the machine is unable to power on, you should try an SMC reset. You can find instructions for that [link|https://support.apple.com/guide/mac-help/if-your-battery-wont-charge-mh29198/10.15/mac/10.15|here|new_window=true]. It that doesn't help, you will need to open the device to do some hardware troubleshooting to determine whether or not the issue is due to the battery or some other failed component. Good luck!
