Where would people who keep clutter due to emotional reasons post?

My big reason for hanging on to stuff is because if I throw it away, I feel like I'm throwing away money, and money is tight these days. I'm afraid to throw out/give away/sell something that I haven't used in 10 years because I might want/need it the next day and then I'll have to pay for it again and can't. Then I'll never have that thing again.

I won't make friends because my clutter is an embarrassement. It's hard to keep the house clean because the clutter is everywhere. I've moved three times since my divorce, and I have stuff still in boxes from the first move. I obviously don't need it if it's been sitting in a box for four years, so why can't I get rid of stuff like that?

Outgrown kid's clothes and shoes. Clothes I haven't worn in years, magazines 4 years old that I never read but might get around to..... you get the idea, right?

Add to the fact that I just hate housecleaning in general and my kids hate house cleaning and my daughter has to hang on to every stuffed animal she's gotten since the day she was born, it's a huge creator of stress.

Now, I'm not like the little old lady with newspaper piled to the ceiling from 50 years ago or anything, but I want to streamline and be like I was pre-kid, where you could actually see the floor and tabletops and there was a place to sit down.

I know there are entire websites devoted to clutterers, but I thought that since mine is tied to emotional attachments, others here might be dealing with the same thing and would be interested in a forum, or know which one already deals with it.
