There are so many things you can do! I like doing chessed in nursing homes in the states, I am planning on doing sherut leumi next year so that I can spend a year focusing on doing chessed. I am hoping to be able to apply to a chareidi special ed gan, the only potential problem is that I am not fluent in Hebrew yet.
You can also; sort out clothes in a gemach, go grocery shopping for someone who is homebound ( I am not saying pay for the groceries, but just don’t charge that person for delivery), bikkur cholim, medical clowning, chessed babysitting, offer to babysit children whose parents cannot afford to pay for a babysitter for one hour a week so that the parents can get some respite (even if to go grocery shopping/ to parent teacher conferences), again, helping out in a nursing home, friendship circle, drive people to places they are doing chessed at, stock a food pantry, tutor a child in a subject you are good at whose parents cannot afford tutoring… I hope these ideas help.
