These kinds of conditions (anxiety disorders, PTSD) are conditions that need to be managed. Seldom do people "rid" themselves of it completely. They're cyclic in nature, you'll experience periods of time where the symptoms are more severe and debilitating, and if you're addressing the issues, you'll experience times where the symptoms are very tolerable, and even absent.
That's why it's important that you find yourself a good mental health professional to help you learn how to properly manage these disorders. Therapy really is crucial. CBT, or cognitive behavioral therapy, which is a little different than the traditional "talk therapy" is a wonderful tool for anxiety based conditions. It teaches a person how to change the thought processes that keep us stuck in the anxiety cycle.
Right now, you're stuck on the "what if I go crazy?" thought process. With the right help, you'll be able to learn how to manage those thoughts and dismiss them.
I recommend that you also browse through the OCD forum, and even start a thread there. The community leader there, JGF, posts wonderful advice and tips on how to dismiss those kinds of upsetting intrusive thoughts.
One of her threads, entitiled "Anatomy of a horrific thought" is fabulous. It explains very well how that thought process works and what to do about it. The key is to not give those thoughts more power, don't feed into them by seeking reassurance, or engaging in "checking" compulsions (ie searching the internet for info, overanalyzing your thoughts). The key is to dismiss them, which like I said, JGF gives really good advice on how to do that.

Hang in there.
overcoming anxiety is dealt with by teaching and practising:
- The conscious ability to relax and release stress any time, anywhere.
- The ability to focus the mind.
- The ability to neutralise and reprogram subconscious "fear memories".
- The ability to develop mind/body exercises to overcome anxiety.
- The ability to develop greater self confidence to experience the situation which is creating fear.
- The ability to program new responses to express emotions in that situation.
