(Serious post from Kevy - I request that you do not post any of this out of context.)
Having feelings of anger, frustration, etc. are normal. While you may be able to "push them out of your mind", your body remembers these feelings (a process referred to as
somatization). If you don't get them out, they just build up inside you, often coming out in wholly inappropriate ways. Some believe (myself included) that these issues, if allowed to build up too much, can lead to and or/contribute to bodily illnesses.
When the frustrations do build up, I have a remedy that works well for me (and others). Beat your troubles out (remember: I am being serious in this post).
It is a cathartic exercise that I learned many years ago. To start, you need to make a pounder. Your best bet is to find an old bath towel. Fold and roll it so that the short side of the flat towel becomes the length of the pounder. Now wrap it up (tightly) so that you have something like a fat baseball bat. When you think you have enough duct tape on it, double that amount.
Now, get an old pillow and a quiet place (preferably with no kiddies or non-understanding folks around). I will do this on my knees on the floor, but you can find other suitable locations/positions. Do a basic breathing exercise to get yourself focused. Three slow deep breaths - in through the nose and SLOWLY out through the mouth.
Now start focusing on all of the negative thoughts that are bugging you. Whether it is a person or a situation, make those thoughts the only thing you are thinking of. Allow the anger to build up inside of you and start focusing it on the pillow in front of you.
When you feel that the feelings are at a boil, start beating the crap out of the pillow using the pounder. Scream your most primal scream, swear, say all the vile things you want to. Get it all out, focusing all of the negative energy on the pillow and beat the living daylights out of it. (BTW: for obvious reasons, don't use a feather pillow!).
Once you feel you have done all the damage you can, then put the pounder down and lay back (or get into some other comfortable position). You may be breathing hard from the physical exertion - that is fine, but you want to try to slow down your breathing as you can. Reflect back on the feelings and what you can do to avoid them in the future. Finally, take slow deep breaths (in through the nose and SLOWLY out through the mouth).
When you fell ready, get up and go about your business!
Doing this once will not "cure" you. But used as an exercise, can be quite useful!
