Fake Friendships?

Anytime i start to talking to anyone, we get so close to the point we text everyday every second and share everything with each other. Lately, everyone's starting to be distant from me? and when i say everyone i mean literally everyone (not over one day probably like over a year and they're not mutual friends they dk eo) even though i've done nth wrong never mistreated them, always answer their texts meanwhile they ignore me and answer to one of my many texts, and are super dry. They were the only ones i talked to daily so it's a hard change, i'm trying to reflect with what i've done wrong on my side but i find none, the only things i think abt is me being sometimes busy with studies so i late reply SOMETIMES and always tell them that other than that i care for the people i love so much, am i being overdramatic abt it and everyone's starting to have their own lives they don't include me in or am i just surrounded with the wrong people?
