I will share a few thoughts and perhaps they will help you help someone else, or know how to answer the questions for yourself, one day.
Use what you have... or what you do.
What I mean is, if you cut hair for a living, offer to provide free hair cuts (not the fancy coloring or Brazilian blowouts) for the family while they walk through treatment. It's a small thing that has a BIG impact. We have been recipients of generosity just like this and it leaves us undone each time. We work to not take advantage of the generous offer, and it's nice to know it's available to us.
Are you an auto mechanic? Offer to service the family's main vehicle so that they can get to appointments without worry. Trips to and from the hospital or doctors appointments adds wear and tear to an automobile... so, it would be nice if the family wouldn't have to take on the task of scheduling and paying for vehicular maintenance.
Are you someone who works with an MLM or a DS company? If you don't know what MLM or DS stands for, you're not one. *wink, wink* MLMs/ DSs are wonderful ways to raise funds for families in treatment! Depending on the type you work with, you could even bless the family with your very products. Ex: I work with doTERRA. I can either do a fundraiser to raise funds OR I can supply some oils (according to what the family desires) from my stock. When doing something like this, be sure to communicate your desire with the family and ascertain their needs/ desires. What you think they need may not be accurate.
Do you do landscaping or lawn manicuring for a living? Why not offer to cut the family's grass once a month? You could offer it for a set amount of time like six months or you could go so far as to commit for the entirety of treatment.
Do you do nails or give massages? Why not offer these services to the family? Every girl needs a mani/ pedi once in awhile, especially while walking through a cancer journey (patient or caregiver). It's a small thing that most women will let fall by the wayside yet it can boost spirits more than you realize. I have been blessed by a generous friend who, for many months, would come to my house and do a massage twice a month. I miss those!
