I feel like a loser!!!?

I am 26, and still jobless, was horribly bad in academics but still managed to get a degree correspondingly at the age of 25. i wanted to be a musician and i was good at it when i was a kid but later study pressure took over my music skills. I tried to convince my parents that i am made for music and i want to learn it and want to make it my full time career but as usual they feel its a crap and its just good as a hobby and not career. and i too feel they are not wrong either, as any parents they too want me to get settled in life with a better career, like in IT, as i belong to an IT field.. but don't know why i just cant think of anything else. recently i learned some programming in JAVA and other few things from an institute thinking that i will learn it and will make a career in the same but after it finished i feel i know nothing about it. may be i am a very bad learner, i always hated reading and these negative qualities will land me nowhere in my life. i don't know what i am doing. i don't know what i should do. i am aimless..completely...any help would be appreciated.
