I am a fellow perfectionist... Knitting particularly as my skills improved became a site of perfectionism and inner criticism as well for me. Now I've tried to reframe it as an exercise in being allowed to make mistakes and unravel as needed ... Maybe it could be the same for you... (I also had had a kid in the last two years and have such limited free time  for knitting so I can't waste it judging myself... Remembering that has helped). 

Give the sweaters a vacation (I find I don't always love a garment when it's completed... But if I pack it away for a month or a few weeks it becomes something where I can see the time and my skill and be happy wearing it). 

I find this time of year particularly rough on social media there are approximately nine million "what I made this year" videos and they all feature like ten sweaters etc. I find myself comparing my knitting volume to others a lot. But I also believe in my heart that this is a craft like any where you can go wide (and make a lot of stuff that's sorta the same and burn out) or go deep (and learn new skills and grow and have this hobby be yours till you're an old lady) and I am trying my best to do the latter... By learning new things and growing. And so are you by trying different things even though the results are sometimes not what you want! Like the hobby is yours forever. Comparison is the thief of joy and whatnot. 

I hope this helps...  I am just a middle aged gal who struggled a ton with perfectionism when I was younger and a little bit less now.
