Almost lost my life

I almost lOst my life and was hospitalized from a terrible accident I am lucky to be Alive but I have broken/crushed bones. My life will not resume back to normal for About a year and I have so much anger built up. When it first happened I stayed so positive and strong. Now that time is passing and realizing how my life’s been changed I am having a hard time staying positive and being strong. I feel like I don’t know what to do
