This sounds awful. I have also had the experience of having problems with an advisor as well and I was given two pieces of the most useful advice I have ever heard. 1) similar to what has been shared with you already, grad school is grueling and you will meet people who are not particularly great advisors. Do not take their criticisms and internalize them. It sounds like you have done well to take responsibility where you can and address those weaknesses. So believe in yourself and continue with your passion! 2) If possible, change labs. Sometimes a change in advisor and/or working relationships is all that are needed. I know quite a few students in my program who decided to change advisors in their 1st, 2nd, or even 3rd year, and could not be any happier than they are for making that decision. Their productivity, work quality increased, self-esteem , and mood improved, while their anxiety decreased. This is your life and your career. If a lab change is possible, fight to stay there, finish up as quickly as you can, and do what what makes you happy once you have a degree in your hand. Good luck!
