Oh yeah, I've been getting this behavior the last few days - if I try to add a react to posts it does this - the session basically become unrecoverable and I have to re-launch my browser.
If it makes me feel bad so I don't talk to people and then I feel worse because of that and so on until I trick myself into thinking I've let too much time pass to ever talk to people again - like I've missed the due date or something.
