I can relate to the situation your are in. Having too many things makes me feel anxious, its not a feeling i like. If i have too many shoes, coats, purses, you name it, it make me feel very anxious, i cannot explain why but the feeling is not a good one.
While letting anything go, i always say to myself, there will be something else that i will like down the road, and that has been true. Return/sell/give away what you do not use. Keep one or two clutches that you would need while going out, dressy kind, keep what you use, that you will miss the most if you let go. I culled the herd bases on this.
I had accumulate more that 70 bags at one time, majority coach bags that sat in my closet in their dust bags, with tags on them, i bought them as they were great deals found at the outlet and i had a purpose for them and i did like them, but i did not LOVE them all...i now own 5 coach bags a few accessories. The money i got by returning all those bags went back into my bank account. I did not do this for financial reasons, but for my piece of mind. That is my story, hoped it helped
