I see. Maybe you can do something in line with your professional work? E.g. if you work with computers you could also help people in the neighborhood. Especially older people often need help.

Another thing I just remembered nearby are repair cafes, I’m not good with electronics so it’s not for me but maybe it’s something for you? Also we have people that help immigrants with bureaucracy, translation or just integration into society (eg. local sports clubs)

Anyways, don’t pressure yourself into something. Just keep your ears open, maybe something pops up.
