Therapy will eventually (with a lot of work) take you to a point where you can deal with it, leave it in the past for the most part and live a somewhat "normal" life. Anthony says there is no "cure" for PTSD, so you will likely need treatment on and off through your life as you progress higher up the healing scale. I go to therapy once a month now, whereas it used to be weekly or even bi-weekly in the beginning of my treatment. I started therapy about a dozen years ago now.
One of the first things you need to learn about is GROUNDING TECHNIQUES. These help you to get your focus back onto the present and are a great tool to overcome the crying thing. They really work, but again, you have to DO them in order for them to work, not just think about them.
Try concentrating on your feet touching the ground or floor. Focus on the temperature you are feeling, the sounds in the environment, what you see in the environment. This will help you immediately to either not cry or be able to stop crying a lot sooner. This is a thing that works now. It will not, however, change your past or lessen the nastiness of the traumas, it just helps you to focus on the present and thus not the past.
Therapy is the time in which you should be focusing on the past, not your daily life. Try this. Until you have tried it and worked at it, you will never know its benefits.
