Rather than overwhelm others that you work with, why not post here or somewhere else where you are anonymous.

You can even start your posts with "Dear X (colleague's job title)" and post away what you would like to share with them. That way others can engage with you or not. They can choose if they want to read your posts.
No one gets overwhelmed, and you can talk about whatever is bothering you. You never know, you may get some great feedback on how to deal with whatever is bothering you.

There are people here who have great insight and a desire to help others. Take advantage of that.
