Hi Glendafitz!
I would like to share a really good way to sort of "tap" that building pressure inside you and relieve it some. A way that has worked well for me. What is this amazing way I speak of? It's journaling!! I have a small 5" by 9" leatherette journal I found at a drug store and it has been a wonderful source of both pressure relief, and of reminiscing about the good times in my past.
I try and stay as positive as I can when writing, and don't often try to write in it when I'm in a gloomy and ruminating mood. It only serves to deepen the depression within in a vicious downward cycle. So for me, journaling isn't a daily activity.
If you'd like, I have a Social Group on this site that, while not very active at the moment, might be of help to you in learning how to journal more effectively. The link to it is in my signature. I hope it becomes more active in the future, and look forward to having made a better journaling experience for as many as possible.
Anyways, I hope you find what you're looking for on this site, and best of luck to you!!
