Hmm. Well, the first red flag I see is that you don't know why you got married. Marriage is a huge commitment. And if you already have commitment issues with your relationships, I feel like you just walked into a ticking time bomb that is waiting to explode. I think people should only marry when they know "why" they are doing it; to be with their soul mate, to raise a family, etc.

The only person's opinion that matters is yours. This is your life. Only you can decide what is best for you and the path that you take. See if couples therapy helps bring some clarity to your commitment issues and your anxiety attacks. I have a feeling that you already know the answer deep down, but need some help getting to that answer.
