Becoming more emotional : listener question

I have been incredibly emotional lately. I cry a lot, actually so much that I am wondering if that is still normal. Also I was very irritated in some situations at work and afterwards I felt like it was really unprofessional to lose my temper.

I think I have always been a very emotional person and my feelings are always very intense. I only let myself have them at home and with very few people I trust a lot. In all the other situations it feels too dangerous and I kind of make sure to always keep my emotions out of everything because I don't want to scare people away or lose control over what I say. It feels like something did break open and that there is something very important and powerful in this, and I wonder where to go with this.

Sometimes I feel like a child that hasn't learned yet how to regulate their emotions, and now that I am writing this I wonder if I actually really haven't learned this yet.

Writing this E Mail also seems kind of inappropriate because I learned that I should't be like this, so I have many thoughts about what anyone reading this would think about me.

As always I wonder if any of what I just wrote makes sense, and would be very happy if you could share your thoughts on this.
