idk my self esteem fluctuates a lot lot lot, so i wouldn't really call it low ,,, i am pretty grandiose tbh

but i get really pissed and competitive over little things that matter to me, such as being more traditionally "small" and cuter than icky ageplayers/ddlg littles, and it makes me behave defiant and hostile towards them, passive aggressive-ly so 

is this a bpd thing? feeling less valid over your identity and getting competitive to keep your identity standing tall? or am i just dealing with a superiority/inferiority complex due to fluctuating self esteem? does anyone else experience similar things?
