Day 1 : Regrets Never Pay-back

Few months back, I bought a motorbike with some financial supports from my parents. Although it is 2nd hand, it causes me RM2000. The main purpose I bought a bike because my university transportation system was really terrible. The drivers are inconsistent in their driving schedule, some even skip few stations , I don't know why? Maybe they just don't like driving a bus, change new work lah if you don't like! I was pressured by my sisters that I should not spend my parents money on bike, so with what so-called GUTS I returned RM1000 back to my parents. Since then, I suffered a lot financially. My stupid motorbike keep on puncture consistently and some other minor repairs carry on for few months. I could not handle my spending anymore, I'm almost broke! Please, god I need guidance. Is it my mistake to return back the money to my parents when they did not ask back but due to cover my ASS ? I'm really in-need for $$.
