So my whole life I (24f) did this thing where I would work really hard towards something then as soon as I'm about to finish or be successful, I completely bomb. Totally ruin whatever it was I was trying to accomplish... 99.9% of the time it's in a way that's totally avoidable and I completely knew better... but subconsciously I just did it.. an example is right now.. I'm in college.. getting my bachelors in criminal justice.. I have a genius IQ.. I'm not stupid. Sometimes the work gets challenging, but nothing I can't take care of... I just stopped doing my work.. I'm 2 assignments behind in two classes. I haven't even started on this week's work, which is due sunday.. I randomly get into these funks and just ruin everything for no reason.. basically my question is if this is a normal thing for a borderline ? 

Just to add.. I will catch up on my schoolwork and get my shit together.. I'm just trying to find ways to avoid the self sabotage to begin with...
