how bad can my life get?

buzzzz.....my head is really spining and throbbing like hell. First of all are my exams, that is the main stressor in itself. Then, my dad had to undergo an eye sugery (monday) - more worries and concern (he's okay now, resting - thank God). And as if all that is not enough, i had to have this strange encounter with a Nigerian guy. Well, it's something like this - monday night, i had to attend some society meeting. My housemate didn't want to go, so fine, i went with some other friends ( not staying in the same area as me). So when it all ended around 8 something, i had to go back alone. On the way back, since i would be passing by a minimarket, i went in to buy bread for the second day. While i was there, there was also this Nigerian guy buying something else. He started smiling at me so i thought 'what the heck?' and smiled back as i thought it impolite to not smile back when people smile at you - and man, was that the biggest mistake i've ever made for the year. He happened to live in the same block and so we took the same path to the lifts. He started talking to me, so fine, i gave short replies. When we got to the lifts, he started asking me for my number. Trust me, i didn't want to give my number at all, especially to a stranger. But he kept pestering me and stood closer and closer to me. There was no one there and i was practically sandwiched between the wall and him. He was so close till our shoulders touched. So having no choice, i had to give him my number. He even called on the spot to checked if it was the right number (he glanced at my handphone to make sure his number was on the screen). So then we went into the lift, at his level, before he went off, he even pat/touched my shoulder and said that he'll call me. I was totally freaked out and scared. Good thing nothing too serious happened. I was so alarmed that i had to talk to someone. I didn't know what to do. One of my housemate was asleep and the other was not back yet. First thing i thought about was to talk to my friend. Good thing i have a good friend to talk to (handphone). It did help and calmed me down a bit but i was in shock. I tried calling my sis but as usual =.= she slept early and when she is asleep she turns off her phone. And my mom was not around. That night i was totally disorientated and couldn't concentrate on my studies at all. I keep dropping things, my heart beated like more than hundred times per minute and my chest felt tight. It was a horrible experience. These few days he called and sms me but i ignored him. I did sent him two sms to tell him to stop contacting me, after that, i totally ignored him. He keep calling (didn't answer) and sending sms saying things like - asking where am i, he wants to see my smiling face again, not to ignore him, and even to the extent of asking me to his place O.o gosh, it's freaky alright. I told my friends about it. They were concerned. It put them on alert too. By the way, i feel better about it now. I'll be ignoring him completely and hope that he'll get bored of it soon. Anyways, as expected the paper for the second day - i think i flunked it. My mind was totally blank. That morning also, our prof. gave us a scolding about our conduct, not being professional etc etc etc *sigh* i really have no comment for things happening to me anymore. Oh ya, and i already told my mom about the Nigerian guy incident. She's shocked and told me off for not being careful enough and for being too naive...etc etc etc...well, i've learnt my lesson. Hopefully nothing else goes wrong....have class in fifteen minutes time...gotta go...
