Venting

My mom just dropped the news to me that she might have pelvis cancer. It shattered my heart. I heard the pain in her voice. I knew she didn’t want to tell me but she had to incase something happens and I am also her rock. I am the oldest and have 2 younger sisters. I moved out of state and I feel so bad not being able to see her more often due to work. I just don’t know what to do or how to be helpful. I feel so worthless. I don’t have anyone to vent to at all.
