I am new on this forum and I have few questions about play script-writing. I am not sure if it is normal or not but the whole play is in my head and I can clearly see my characters talking and moving but again it all happens in my head only. I know the whole play but it gets complicated when I start writing. However I am aware of the fact that transferring this from my head on to the paper is an art called script-writing. So my questions are

1: How much should I give stage directions?
2: Can I add inner feelings of the characters on the script?

I will be grateful, if you kindly share your tips and tricks that can help me finishing my play.

Thank you so much for your time and looking forward to hearing from you soon.
