It's okay, I think you need to take a break and give yourself a bit room to breathe! I always go through that stage when posting something, I grow to hate it, think it's not finished and I can't seem to click the ,,post,, button. It always helps me to first get a good nights sleep in and the next morning you're more levelheaded and can see if you made any errors. Overworking yourself results in errors you wouldn't otherwise make, I've been there. I'm also sorry to hear how you feel about yourself, I get that this field in particular can be exhausting and competitive. But at the end of the day I'm sure someone will want to hire you, you don't need perfect projects you just need to demonstrate consistent work and seems like you've been to college so I'm sure you have a lot of hard work behind you already. And I'm one who also suffers from being to self critical and obsessing over the smallest things in projects, but you have to let go at some point and say to yourself it's time to move on to the next project and give yourself room to grow in-between. If you like you can share the portfolio when you publish it , maybe having someone here see it first and give you feedback will be less scary than companies.
