I never feel energized

Andd....there's a lot of factors, without talking too much, most of my friends moved away, I missed out on a lot of childhood experiences, I was the Middle kid, I...happened to be born a bit emotionally sensitive so I feel everyone's vibes as intensely as I feel mine T^T, I consistently have been struggling with dealing with a difficult brother i wish would become more pleasant, and parents that are in denial of protecting them, because of the lack of a experience full childhood I view adulthood (I'm 18 rn T^T) like haites, I'm uncertain if I wanna run from it or submerge into it and just....idk?......there's too much on my mind, and it all makes my energy levels even worse because I go by logic, "Problem? Cool, fix it", I can't fix these problems, and the people causing it can't fix it either

(Sorry for anyone reading this, no pressure to respond TvT.....I...talk a bit much)
