So if W bosons decay so quickly from what are new W boson made? Is it made of an electron and anti-electron neutrino (which is what they decay into) but then again this wouldn't make sense since it is an "elementary" particle. Please clear my confusion.

W bosons are elementary particles, they do not "contain" anything. They can be created in high-energetic collisions, if a lepton is transformed into a neutrino (or vice versa), or an up-type quark goes into a down-type quark (or vice versa).
