I don't think I have any really good advice here, but I'll try.

First, accept that letting out those bottled-up feelings is going to feel yucky for a while. Then just let it happen.* When you want/need to cry, do so. Journal about what's on your mind and what you're feeling. As you move through these repressed emotions, forgive yourself for having them. Forgive yourself for your part in the creation of them. Accept that you are human, and as you stated, we all have our "stuff" to deal with. It's being human.

I can't overstate the value of working through repressed emotions/thought/issues. You'll be surprised at how different you begin to feel as you do this. I wish you the best of luck.

*Note: Given your daily life - work, etc. - there may be times when holding back emotion is appropriate. Please don't put your job or anything else important at risk by emoting all over the place.
