Is there a thing called unlucky phone?

Ok since the day I got my iPhone 6, there was something wrong i could feel it.
3 days later. My phone screen cracked.
Next day got my phone screen fixed and my screen lifted up. They forgot to put in one screw beside the charger thing.
1 week later my sister broke it again.
1 month later my sister was looking at it and dropped it.
I don't know what's wrong with this phone.
I was going to go to apple store to get it professionally fixed but then I said what's the point its just going to have more problems.
