Can I just cry already because I think it might help.
Oh? You want to cry? Is that right? Why are you having so much trouble with crying right now?
It's just difficult for me to cry sometimes.
Crying is a perfectly acceptable response when you feel emotionally overwhelmed. Sometimes crying is really beneficial, so if you feel like crying then you should.
I need to be more open and vocally express my emotions.
Crying is a natural emotion. It should come naturally and not forced. If you can't cry right now, maybe it will come to you later on.
