sorting the junk

I have too much clothes, and at least 89% of it is either too small or too worn out and ugly to be worn. Yet they are cluttering up my space and making it difficult to just put things away. It is depressing and I tell myself I need to sort it out, but the sheer volume make me tired just thinking about it. In the past when I have attempted to de-clutter I have spent too much time dithering over whether a t-shirt that is a little too tight would be okay for gardening in and I really should keep it just in case. I also tell myself that I'll slim down and be able to get back into those beautiful Miss Sixty jeans that are just too good to give away. Hence the mental torture of 'should it stay or should it go' halts any notion I may have of sorting the junk.
