Do Movies Make You Cry

Just finished watching a movie, parts were sad… I cried and cried realising that I have been missing my Mum. I've been sucking it up, trying to be strong… to move on… I think I'm a little scared that if I allow myself to cry that I just might not stop… Like when I released all my hurt and pain when I wrote my autobiography… I cried a lot then too… ?
I feel peace within. I suppose it just all takes time.
