Getting crazy? please help?!

Getting crazy? please help?

I suffered from depression and anxiety a year ago. Now I am so much better, but the other day I got this strong, horrible feeling/thought that I was getting crazy. I mean real crazy. I felt that I was going to be mentally ill the rest of my life. It was like a panic attack, but instead of having the typical symptoms (heart racing, chest pain, shortness of breath) I would get this strong thought. After a while it went away. I would like you to tell me what exactly is that I am having and how to prevent it. Please help.

I have panic disorder and have strong thoughts often, probably just another symptom.You will not go crazy, it just plays with your mind.
