Suppression

Suppressing anxiety, feelings. Do we really have to do that? Well, in one side of the river it helps to keep our cool, analyze the situtation to the depth and then take decisions so as to make it a win-win situation. On the other side of the river, doesn't it builds up the feeling that something inside us is controlling us and adding up to the psychic storage, once when filled can be a destructive if not properly expressed. As an exmaple, won't the feeling of anger if supressed will one day eventually blow up recollecting all the past incidents? Do we have to really suppress those kinda feelings? I guess it has to be a mix of both, to swim along with the river of life.
