Don’t feel that you have to play, that only puts more unnecessary pressure on yourself. Playing bass is like falling off a log; you’ll be surprised how easy it is even if you’ve not done it for a while, your mental health has to take priority here, don’t beat yourself up for not playing. Take a walk outside or get a bit of exercise (I know this is difficult to do too, so these are just suggestions), anything really, just don’t pressure yourself into playing, it’ll still be there when things pick up.
