to be left alone is painful. however, we should not base our happiness and our life on others. dependency is paralysis. you should also be happy that now you are given the opportunity to be on your own and experiment life on your independence. i'm sure that there are reasons for everything that happens in our life.. i really believe in that saying that we are not given problems we cannot handle. siguro pag una lisud pa, pero once you believe in yourself, you will be thankful later on for all the pains in your life..
i really don't know your situation. so i am speaking in general lang. ciao!
