Thank you for the response.
Full disclosure before reading the text below: I am not suicidal now nor do I have any plans. And intellectually, what you're about to read is indeed irrational. I've had (former) friends try to help me then criticize me for how irrational my thoughts can be, so I always feel the need to qualify irrational statements. With my therapist, I tend to be much more open.
When I "feel the fear," the most common reaction is suicidality. It's as if I have a voice advocating that should kill myself because I am not living up to my own standards. Or maybe it is the standards of others I am really concerned about?
If I were to ask a so-called "stupid question" in class for example, I would think I should kill myself right then because clearly I am inferior to my peers, and I figure at that rate I will never be as "good" as them, so why bother. I then start thinking about all the mistakes I've made: past substance abuse, skipping class, dropping out of school, while completely ignoring the negative times I was going through then, as well as the positive improvements I've made since, such as being readmitted to school. I recently quit smoking marijuana again for the Nth time, so I'm hoping it sticks but I have a lot of guilt about this as well, since I've been using it to self-medicate now for about 4.5 years. I think: "How much better could I have done if I hadn't had these problems? If I had parents that truly cared about me? Maybe then I could be as talented as these other students, or have good enough credentails to go to graduate school."
Conversely, I tend to be filled with pride and grandiosity whenever my performance is superior to my peers. If I see that I'm outperforming others, I often feel superior to them and derive a sick pleasure from putting them beneath me in my mind. I also feel superior to students with other majors with lesser job prospects, and this is something I tend to remind myself of daily to keep what little semblance of self-esteem I have. It's one of my worst traits in my opinion, I think without this I wouldn't be so hard on myself either.
All throughout my childhood, I felt like I had to be the best in school. In high school, my class rank was #1, but now I'm at a top university in the US experiencing the stereotypical feeling of a little fish in a big pond. With the abuse from my father, I was desperate to do anything I could to earn his love, and I think part of me figured that if I did well enough in school he would treat me with respect, since that was an area he tended to compliment me in. I always felt threatened that if I dipped below the average, I would lose the love and affection of my family, or worse yet, become like my parents who never did well academically.
Those are the general themes my thoughts and feelings lead to.. I am sure there is more I haven't thought of.
