Hoarding problem?

So I’ve always had trouble getting rid of stuff. I find sentimental value with almost all of my belongings which sucks because when my place was clutter free and I hardly owned anything I was so much happier and felt so much healthier and refreshed. Now 7 years of living on my own with my 2 kids and hubby I’ve accumulated a lot of clutter. Like a lot and it’s giving me anxiety. I want to get rid of half my shit, preferably more than half haha but I just can’t. Today I was cleaning out our bathroom and came across a stash of about 5 of my sons old tooth brushes. I went to throw them out then had second thoughts about it and took them out of the trash. Wtf?! Second thought about old used tooth brushes. I don’t even know why I would want to keep that or why I would even think twice about throwing them away. I mean they are the cute little kids tooth brushes that spin, play a tune, or light up haha but still. Yuck! They’re no longer usable so why the hell do I want to keep them? After that little incident I have come to believe that I just may have a bit of a problem. Ugh I can I overcome this? It’s like a part of me says get rid of all of it but then the other part is like ugh that was special before, or on I could use that again sometime in the future or oh that has so many memories attached to it. 😓 it’s exhausting.
