My dad passed away from lung cancer last year. It's almost a year, It doesn't feel like a year. I feel so lost without him he was my best friend. One of the only people I ever truly trusted and confided in. It's completely changed my outlook on life, the way I treat other people. While I appreciate the people around me sooo much more; I miss him, I feel it in my chest everyday. I just don't know what to do now, the feeling doesn't leave. I feel so lost right now.
