It's ok to cry and let it out. In fact, letting it out is exactly what you should be doing. Just don't do it in front of her.
Yes. Letting out your emotions is the healthy thing to do. Find a safe place. Make a time for it.
Need to express some anger? See if you have a "rage room" service in your area. I haven't done it but I think it would be a great experience.
Need to cry? Rent Marley and me. It should trigger the sadness. The trigger doesn't matter. Letting your emotions out is what is important. Watch it alone and let the tear fly. Embrace the process. Feel the pain.
We have been where you are. It is normal.
