I don't think you should keep stuff buried. The best way to deal with a lot of that stuff is to have a creative outlet. Do you draw or paint or play guitar or write? Find something creative to do. Don't worry about if you do it well -- you only have to do it for yourself, not for other people to judge. If you learn to free your mind and just create what flows from your unconscious, you will deal with things you might not have even known were there -- and you'll do it in an enjoyable, natural manner. Don't start out with a specific goal in mind; just let your mind roam free -- you might be surprised to find joyful things in there, as well as the painful ones. Start a journal, start painting... something creative. It will help.

And, of course, there's always a C, T or P.

As for forgiveness, don't make more out of the word than it is. Forgiveness does not mean you have to feel all warm and fuzzy about the people who have done bad things to you. It just means you come to terms with what they did and how it affected you and you're moving on with no ill feelings toward them anymore. It doesn't mean that you welcome them back into your life (unless you want to) or that you are dismissing the hurt they've caused. It just means that you refuse to live with the hurt they inflicted anymore.

It helps to realize that most people who hurt others are unhappy themselves, and are working out their own unresolved, unconscious issues. If you look at your own life, you will probably see where you've done less than perfect things yourself. As you learn to see why you made your own mistakes, and you learn to forgive yourself and move on from your own mistakes, it will become easier to forgive others and move on from the hurt they have caused.

But to "deal with it" and then heal from it is not an overnight thing -- it takes time, but it can happen.
