Should i start over again?? pliz help me. ?

so, i am an uni student studying economics. tobe honest, it's not my favorite major. i lately find my self interested in design graphic. although i cant draw very well, i still like it. i love designing stuff like magazine cover or books. i love operating adobe indesign so much and been spending my time try to master it. mean while, i also like music. i saw a movie yesterday about being a music writer and then i feel like i wanna give it a shot.lol. dunno. i even think about purchasing a keyboard. is it awkard for me to feel that way? tobe true, when i finished high school the first thing i want to do is to go to the design school, but i cant afford that much. for this years, i have buried my dream and pion in grave. mean while, my fam have such a big hope in me that i could make some money after graduating. what should i do? i cant see my self working as a office worker in the future. what i want is tobe a designer. do you think i should start over again? or what can you suggest me? i can really use ur help. thanks. (sorry if i'm whinning too much, lol)
