I´m sure it is not... you just have to overcome your personal issues :c.
Is there maybe a possibility for you to make a praktikum or something fo that kind (something in a direction that would count in your studies, to not have that much pressure and just do something)
Perhaps... I don't want to take a traineeship that another person might need more and I can't take that kind of an offer and say "I'm actually just doing this to overcome my lack in motivation, but I can't ensure you that I'll be productive." I'd be that honest...
