You don't always have to pretend to be strong, and there's no need to constantly prove that everything is going well. You shouldn't be concerned with what other people are thinking either. It's healthy to shed your tears. The sooner you do,
Always find something positive away from negative. There's always good things to follow that's very much important. Trust in being you. Don't let the things you wish you can fix drag you apart. Time will take time for things to be fixed out of difficult horrible times.
