I don't know if this will be helpful, but when I was in college, I failed a very basic CS math class because I was very anxious, comparing myself to others, feeling inadequate, feeling like I had wasted my college tuition (I took on a lot of debt, and my family isn't rich. The whole reason I got into this was for some semblance of financial security.) I thought I had ADD and that maybe if I got diagnosed I would be able to get some of those magic amphetamines that everyone else seemed to be using. Instead the psychiatrist I saw recommended I seek therapy for anxiety and depression. I was putting so much pressure on myself to succeed and take care of my family that it was impossible for me to succeed in school or even really live my life to the fullest without addressing my thought patterns and emotional state. I don't know your situation, but there are plenty of respectable jobs you can get with a CS degree without being a master of CTCI. It won't be Amazon or Netflix but it's okay, most people don't work at a Facebook/Amazon/Apple/Netflix/Google.
