Hello RockMaterial and welcome to the forums.

Only a qualified therapist or Pdoc can give you a definitive answer as to whether or not what your experiencing is normal. I've known people who are not very emotive. For some it's cultural. For others it's the way they were raised. You said that when you are forced to talk about your emotions that anger and sadness get mixed up. Just a guess here but, could some of the anger actually be from the fact that your being coerced into talking about your sadness when you don't want to?
