Breaking through an Emotional Wall

There are times when I just want to cry. I feel as if ... if I were to cry then I would feel a little bit lighter, as if the weight on my chest and shoulders would get lighter. I was told once that this was a good immediate cooping technique. In the past, I would watch movies with super sad parts (parents/friends dying, loss of something, etc) or something super happy (military personnel returning home from deployment, proposals, etc) and those would help. My go-tos have not been helping recently. I was wondering:

1. Does anyone else do this?

2. Any recommendations?

Thank you in advance.
