Wishing the world was a better place

Hello I am feeling stressed and angry about this world and I talked about wanting to harm or kill myself because of me not being able to cope with life any longer as I really wish that nobody was born disabled or differently from everyone else or no one was to become disabled later in their lives in the future as I really wish that would never happen as I hate it when life is so unfair and people try and make me accept things like life being the way it is when I should not have to accept something like that as disabled people cannot do anything for themselves like defend themselves so I just want something to be done about these issues like curing and preventing disabilities in the future, God to make life better and to sort it and for everyone to make this world better too. Also I would like for people to never be moody towards me at all anymore.
