I agree, having grown up similarly. It's very important to be able to grow roots. Not being able to because of frequently relocating can cause a permanent feeling of being disconnected throughout adult lifehood as a result.
No, that's what you're experiencing I think. And 'news flash' makes you sound very condescending, can't help but wonder if this was intended.
Anyway, you might feel disconnected. I actually was disconnected, multiple times, from my friends, environment, and had no other possibility but to start from scratch. So I don't even understand why you feel the need to compare, to be honest.
