Newlywed Doubts

I just recently got married about two weeks ago. I’m a 24 year old female working and attending college. I have had rocky relationships in the past and now I’m married to someone whom I dated for a mere four months before marriage. I think I made a mistake because I never believed in marriage and now I’m in the institution and feel totally depressed. I don’t think I’m marriage material and I don’t want to be. I feel terrible about it. Is there something wrong with me because of not wanting to be confined to the institution. I feel caged now…. I feel no longer free in my mind.
