MMS and your social phobia are unrelated.
Do you have any idea how your phobia originated? Do you just not fit in well? I'm 24 but am often told I have the mentality of an elder because of how I look at the world, society, and overall wisdom. I would love to try and help get to the root of your issue with you... but you would need to express a willingness to open up, be honest, and go beyond your comfort zone if necessary.
I'm no psychiatrist or psychologist but I do like to help people.
This isn't the forum for it, though.
