Hi and welcome.
I have been diagnosed with schizoid pd, and from what you say I think this could be fairly accurate for you too. Theres a lot of reason to feel hopeful, ...

I often become aleinated in a group and feel isolated, see things differently from everyone else. I also was a left out type of person at school. Its not easy, painful at times in life.
another term for schizoid is 'self in exile'. The flip side of the coin of that is the delicacy we have ineternally that makes it difficult to protect ourselves, our boundaries in relationship to others.
I have a lot of recovery compared to how things were, but still a long way to go also...
pm me if you would like to, you could also check out this website:

www.selfinexile.com

as well as this, there are some Ts who are specially trained and who have a lot of understanding of this disorder........ I can give you more info if you'd like.
