First, I guess LZ is still young, I mean u r still going to school, if not, I'm sorry.
People around these ages are still lokking for what they need and what they want; just like you might still thinking which courses u r going to take and good for your future. When u go out to work, u might change few jobs before you settle down the one for the rest of your life. Therefore, what u need right now is see more & learn more, and treat yourself good (ALWAYS).
Never compare how much u gave or received, b'coz LOVE is always not a fair game, and there is no rules for that as well. Take care!
