What to sell on eBay?

[Fred]

Basically, I am 15 years old and live in the UK. Since they do so much already I really hate asking my parents for money and have done for as long as I can remember. This has made an impact recently as I have lost numerous friends through turning down their invitations multiple times to go out somewhere, because I don't like to ask for money. An idea sprung to mind earlier about an eBay business but deciding what to sell is proving difficult. Would it be cheaper to sell handmade things rather than buy things at a bargain and sell them for a profit? I am good at arts and crafty things if that help. I need ideas please.
