This world has always been so cruel to me. I have given up on life. Now, I'm planning to leave my home and live my rest of the life in orphanage/Housing home. So that my parents/siblings won't get upset by seeing me in such state all the time. Is this step right islamically?
Sorry to read that. I cannot give you any specific advice without knowing more about your age and situation, but what you are suggesting (of leaving home) sounds like almost certainly the wrong thing to do. If you do not like your present situation, think of the possible solutions then consult with your family and relatives and maybe a solution will be found. Since your decision affects your family, this is not something you can decide all by yourself.
