Double eyelid to triple eyelid

On saturday, when i woke up, my eyes were very tired and heavy and i felt really uneasy but i didn't really bother because i thought it will be better in the afternoon. But when it came to the afternoon, it was nothing better and it was still very heavy. But i didn't know what went wrong. Well, on sunday then i realised that my left eyelid had some problem. My eyelid was originally double eyelid but somehow, it became triple! Seriously, i have totally no idea what happen and it looks weird and makes me really uncomfortable. On sunday afternoon, i took 5 - 10 minutes of my time, standing in front of a mirror trying very hard to change the triple eyelid to double eyelid. Well, it somehow succeeded. But the eyelid got back to triple when i bath at night. Today, when i woke up it is still triple eyelid and i really don't like it. It is not the appearance that i bother the most but it is really uncomfortable. The eyelid became heavier so it tends to lie on the eyelashes which makes my left eye really uneasy and it make me feel like rubbing my eye. I don't know if it is lucky to have it only on my left eye only or not. I asked my mother why did my eyelid turn from double to triple and she gave me 2 reasons. Firstly, it is because i have insufficient sleep. Secondly, it is because i have too much sleep. Well, i think that the second reason is more likely to be impossible because i always have insufficient sleep instead. So, it should be the first reason. But is there any ways to change the triple eyelid back to my double eyelid? Well, there is no harm telling me the solutions because i really find triple eyelid UNCOMFORTABLE!
