Most Helpful Guy
That is actually a lot more common than people realize. There is a very real human need to connect to others, to feel that sense of connection and acceptance, to know that what you are doing, or what you are thinking, or what you are feeling, is ok and accepted.
If you do not have a peer group that thinks like you do, or that has the same interests as you do, it can feel very isolating, and it can cause a lot of psychological trauma.
This is part of the reason why people with higher intelligence, or higher creativity, are often more depressed. It becomes harder to find people that 'get' you, hard to find a peer group that understands where you are coming from, and that makes you feel like you are ok for thinking the way you think, or acting the way you act.
There will be someone, somewhere, that can relate to where you're coming from. Someone that will be able to see things from your point of view, to accept the decisions you've made, and possibly help you better understand yourself in the process. If you are feeling that isolated in your 'home' life, you may find someone more understanding online, through some kind of shared interest site or something.
There are ways to get through the issues you are dealing with. You are not alone (though you may feel that way), and there will be a solution. It just may take a while to present itself.
