I hope you'll feel better soon.
I was also sad when I was doing the job search because a lot of companies rejected me. I felt I didn't do well enough, or maybe something's missing in me. Although I know I'm doing well in my job, the rejections says otherwise.
Fast forward, I got hired and is doing well now. I think it was the right timing to get this job. Everything just fell into place.
I hope it will also happen to you soon.
Don't give up just yet. I believe you are doing well and you are really artistic and creative. You have a lot of ideas, and I'm sure you'll land on that job that is meant for you.
Take it easy, my friend!
