I have an extremely hard time with jealousy as well. I can totally relate to what you are feeling. I work hard to control my jealousy because I don't want to lose my boyfriend (or friends). I find reading articules or books on the subject help, but it takes alot of willpower and dedication to be free from jealousy. Mostly you first have to figure out why you feel jealous. It sounds to me that you feel excluded from things you feel you should be or want to be a part of. That is understandable but not completely realistic. You insinuate that because they didn't call you they must not like you as much and that you are boring. That is not them saying that it is you. To overcome jealousy is to look deep inside yourself and face your fears and insecurities. Look up some articules or books and read them, they will save you alot of heartache that you don't need to go through.
