Very tough and it must seem that it's hopeless. Please believe you will be happy again This is an incredibly tough time and you have no choice but to endure it Their is one person who can help you with this and it's you you have to deal with this situation Get all the support you can and move forward. Like everyone I want the pain to go away but it takes time. Move on now. There is always hope and this need not be the end of your R. Live your life. You are a young man and have a lot of living to do. Be good to yourself.
