I am having real problem with clutter. "Stuff" sitting around house, cute nic-naks, other stuff. I hate holding garage sales. Lived in my house 50 years. I need help. Driving me crazy? Any suggestions?

You could sell it on eBay! See if your friends would like any of it and donate the rest!

So after you have given away a lot to your family and donated some to various places like my friends said, go out back and push your trash can next to your back door. Now throw out your stuff. It will be hard at first but if you haven't used it or its broken or tattered, dump it. If you have to, have a huge trash can delivered to your house. You will feel a lot better after you purge your stuff.

Remember that every time something comes into your house something has to come out of your house.

It's a hard thing to part with your small treasures. Each piece, I'm sure holds a small story about how you found it, where you picked it up.Sometimes inviting a friend over who can be a little less emotionally attached to the items and perhaps they can help you sort them out. Help you decide what can and can not be given away. This sounds weird but taking a photo of some of these soon to be given away items can help and photos are much easier to store and keep. Remember these are only things as you try to remove your attachment to them. They weigh you down, clutter your mind and make house cleaning and maintenance difficult. If you don't have a friend willing to help you, there are outside people that you can hire, professionals who can help.

Stop hoarding give it away you cant take it with you

You could give all to a homeless shelter, women's shelter, garage  giveaway and  your church. 

Goodwill and Salvation Army.

Donate it to any charity.

Donate, give to loved ones, sale online or at something like a flea market.

Personally, if I try to horde my unnecessary belongings, I throw them away. If I don't do something quick like that I will try to find reasons to keep them

I share your pain. We've been in our place for more than fifty years, too, and the clutter is amazing. Like you, we don't like garage sales so we just donate it to the opportunity shops -- mostly St. Vincent de Paul or the Salvation Army. They don't take rubbish, of course, but our council offers trash pick-ups twice a year so that we can get rid of it.

If you want to get money for it you might try eBay.  I really don't know much about that but it's obviously very popular.
