You set all this up so that you would learn from it. If you give up without learning the intended lessons, guess what: you get to do it all over again.
Your Mom sounds like a real pill. Ignore her. You are everything you need. All the energies in the Universe are just as available to you as they are to the jackoffs who bullied you. They'll learn their lessons eventually (oh yes) and you must do the same.
Like attracts like. Forget wanting a Jaguar...how about some peace? To get that, you must be peaceful. Want Love? Be loving - to yourself, at first.
Don't you let them win - they are manifestations of the parts of yourself that you need to transform. Don't ask the Universe for joy...you'll just confuse the poor thing, because joy is within you and instantly available.
Peace and Blessings, son.
