being sensitive

i juz need a break from everything..stress with work, stress with r/ns..y am i such a failure when handling with small issues..y am i so sensitive and thinking alot when he is out all day..i misses him way too much, just needed to c him online and at least accompanying me a while, without doing anything..however, my realisation for him was, when he's online, he's simply either busy browsing website or else not paying attention to me and just ans me a simple ya, yes..i feel tat sumtimes i just needed some1 who could at least gif me some response..im angry tat he doesnt manage his time well, he doesnt keep his promises, y r guys always like this..when say they be back by this time, they fail to keep it..sumtimes im just angry with myself, y muz i flare up with him at all, am i a really bad person..haiz..life really sucks to the max..
