Again it sucks to be me

Don’t know where to start this from, today I am truly upset disappointed with everything in life even myself, have been a total loser all my life and would remain one.
It amazes me how do parents know what’s good for there children maybe experience but then they say times change, people grow older and gain experience, they love others , they spend there life and then they live for there dependence , they say that love of a parent is unconditional and it goes in without any expectation then why do parents always demand things, why is that a child can ever live for him/herself . Today all my misconception are answered that no love is unconditional and that it will always remain a give and take relation no matter what, why do people who have lived there life decide on life of the person who is about to start his/her life. Are we humans or are we cattle’s , even they are better atleast they have a life of there own unlike us humans who are more into selling of human as product than humans…don’t u think that it is time that we start behaving as humans…my relations don’t last but then I always want them to be , but for parents the relations would always suck and would never last
