"can't get you out of my head"

Ok... I'm really pissed off. I dont know what is going on. He hasn't given any sign of being alive since Sunday evening. Is he trying to punish me for not replying or am I just freaking out? I'm really getting crazy and imagining the worst things (i.e. he's punishing me and that's why our relationship will not work because I've had such experience with my ex and I don't want to have such dramas anymore... aaaaaaaahhhhhhhh!) I wish I could stop thinking about this and just get back to work but I guess it's not possible! God!!! I hate feeling like this...
