<human>: Can you give me the gist of the text in a nutshell?

I am at the end of my rope. Academic decathlon is the reason I enjoyed high school for the past two years. But all of my friends have graduated, I'm not interested in the topic, and I do nothing to fulfill my role as captain because the coach has worked against me at every step. I'm even competing at a lower level than I should be, so nothing is particularly motivating.  I don't know what to do.

 I haven't actually done any studying at all and our competition is in two months. I don't want to keep doing it, but my dad says it shows a lack of character and that since they're counting on me I should stay. I really think that being stuck in this is contributing to my being depressed. I want to leave it so I can get a job but I don't want to be selfish. What should I do?
<bot>: sick of acAdec but staying out of obligation. Desperately want to leave, but I feel selfish doing it.
