You’re most definitely not alone in this regard. One of the ways I work through it after a bad drawing is by making an effort to see what I did “right” in the drawing. It’s definitely not easy because we all have a tendency to only see our mistakes, but if you make that effort to see past them you will see that you did some things the way you intended. After that, identify one thing you didn’t like about your drawing and focus on that area in your practice.
Also, you need to cut yourself a little slack and remember that you’re in the learning stages of a really complicated process. Art is hard. I always compare my work to artists that I respect and find I come up short every time. I just have to keep reminding myself that learning to draw is a process and if I work the process one step at a time I’ll eventually get to where I want to be.
Just remember what the great Walt Stanchfield said, “We all have 10,000 bad drawings in us. The sooner we get them out the better.”
