bad days after good days

why can't i have just one single day and everything will turn out right. i had a very bad telephone conversation with galvin earlier, around 7am. yeah, a worst one. for the past seven months of going out together again. i can say that this is the worst fight we had. i yelled and nagged on him on the phone and he did it too just because of a simple and no sense reason. its the first day of my period now and i admit that i got easily annoyed and my mood swings ever now and then.and then again, i intend to say harsh words which i did not mean at most. and most ofthe time, i regret after i realized that i was wrong and that i talked too much i really dont know how will i convince myself,, to admit that it was my fault and i owe himan apology. :( he called me up late this afternoon asking for forgiveness about what happened this morning and i hated him for doing it. i feel like he is making me realized that im a very bad person that i couldnt afford to apologize eventhough i have to. that he must do it first because he expects that i am not that kind to do it. grrr even me, i cant understand why i am acting so weird. he wants just to settle things..thats it! why cant i just simply understand it? the problem with me is that i always overanalyze and justify things on my way. i am so close-minded and unreasonable sometimes T-T yeah thats my problem..and because of that, i failed to appreciate the good things that he did for me.. i never even bother to say thank you when the time that he took care of me when i got sick. i forgot to appreciate little things he did yet very meaningful such as massaging my hands and even my feet on my tired and stressful days..damn me..im so mean. and now what? after all im acting all weird, im hotheaded. im annoyed. im irritated without giving him the reasons why., T-T
