Ok, you don't want stuff, but spare me the stress you feel around your family/others not understanding you. Use your energy in a more friendly and giving way and maybe you'll find that it's a bonus to receive the chance to get out in your community, meet and share and give to those that could use a leg up.
I bet once you cycle back and tell your family and friends about the people and places and experiences you now have after donating things, they'll understand. Some will have a hard time with it, but I doubt for long.
I get a bonus item every 5 yrs at my company. Couple years ago received a 60" TV, took me all of a minute and one email to a local school in need and they drove over and picked it up.
