I know its stupid but it gets to me...?

Im only 16 and im so desperate to find love, i see these films and programmes of happy couples and im so jealous! I see boys too and i feel like i want to approach them but i feel silly! Ive had four boyfriends and my most serious one lasted for only half a year but i knew i was in love and i wish i could find what we had there but even better, sometimes i feel that boys are a waste of space and i got so paranoid. I just want to be loved :( Help... i need to get over this!
