Hello lindammarie: Welcome (back) to PsychCentral!

In answer to your question... sure! I don't see why you could not get support for decluttering your house & office. (Actually my wife & I have the opposite problem. We tend to get rid of anything & everything we don't seem to have an immediate use for. I've divested myself of many things, over the years, I now wish I had back!)
As I'm sure you're aware, there are many members, here on PC, with many diverse interests & experiences. So it's likely there will be other members who will share your struggle.

It can take a while to become recognized, & to develop a following of like-minded members. But if you keep posting your own threads, & reply to threads posted by other members, you're sure to find the support you seek, I believe.
