I really co-sign both of these! I'm fortunately more addicted to thrifting clothes than buying new, but I still have to stop myself and consider if I really really need yet another pair of jeans (I absolutely don't!).
And #5 - oh boy, yep. I love how I look in clothes and in turn, how clothes look on me (I had no idea that under all that fat was a pretty good "coat hanger" body), but out of clothes is another matter entirely. The loose skin isn't super bad, but it's enough that I'm self-conscious, and I'm now also conscious of how bony I am. I suspect I'm on the cusp of being told I'm too thin, despite still being in a normal BMI. I've basically swapped one body insecurity for another.
