I have felt like that for years.
I have been overweight forever, even though as a kid I would play outside constantly, ride bikes, kickball,basketball didn't matter I was fat, and I been like that all my life (47 now), and what really pissed me off the most, I had a friend that hated excercise of any type, would eat like a pig, more than I ever did, and was always skinny.
I never luck out with jobs either, where I had people I knew that would luck out and get great jobs, I always got deadend jobs that went nowhere, just recently the job I had for 7 years that I loved, even though the pay wasn't great and I got great yearly reviews was eliminated so I was back where I started.
I never had a girlfriend, or anyone that was anyway attracted to me, I have been alone all my life, even my parents were gone by the age of 26, my friend gave up and got a mail order bride, but that is something I just don't have the money for, I have pretty much given up, when I was 14 I had a vision I would be alone all my life and learn to do things for myself, I right then went to my mother and asked her to teach me how to do laundry and cook etc, enough to get by, good thing I did, that vision came very much true.
I would have something good happen, I would be happy for a bit, then something bad would hit right after, now when something good happens I never get happy, because it never fails something bad would follow suit. Case in point, I finally got out of a financial issue that was haunting me for years, soon as I got out of it, two weeks later my job downsized me. I was like really, not even one year of being happy?
So yes I felt cursed all my life, I told a coworker once I must have been Hitler or someone equally as bad in a previous life and this is the punishment for it, or I did someone really bad somewhere down the line and got a gypsy curse or something.
I have many times looked at the sky and apologized for anything bad I ever done that might be causing this kind of bad luck, but so far nothing. Some people don't believe in bad luck or someone being a born loser, but after all these years I really think it can happen to a person, especially when you see other people always come up smelling like roses no matter how much crap they fall into.
