It's been mentioned a few times already but I just wanted to +1 the suggestion of considering therapy. And I don't even mean that in a "you sound like you need therapy" sense; I think therapy can be a great tool for anyone trying to improve the way they handle stresses like this, regardless of whether you think anything is "wrong" with you (e.g. depression, anxiety, etc). I have struggled with fairly severe anxiety at points in my career/life, but therapy has just generally helped me a lot with handling stress, not taking things so personally, fighting procrastination, not coupling so much of my self-worth to my work performance, etc.
