If you do feel like that, decide to move on !!! Do you know how powerful is that?... you are the one who gets to decide, no one else... and you have always the opportunity to try again and again and again and again and again and again and again... ... ...
Actually, these days I don't feel like that anymore. I'm happy no matter what, and this doesn't mean I don't care about things happening around me, It's just that I feel I am more helpful if I come from a happy place rather than a sad-upset-nervous one. Soooooooo... the trick (for me... and I'm pretty crazy) is not to "have low expectations" I can have the greatest expectation because I don' tie my peace of mind in getting what I want... and even if I don't get it... how on Earth being dissapointed is going to improve the situation?... I prefer to start doing something else (now that I know that what I tried before didn't work... how wonderful !!! now I know what I don't have to do !!! =p ) to achive that thing I want to achieve and BUM !! and don't even have time to get dissapointed ^^
