Lost them

It was 4 years ago, we were really close, almost everyday together but then when you got older, each one of us kind of have different friends but at least we stays friends. But 2 months ago (it was my birthday), but out of 11 in my group only three congratulate me (I'm really sad that day because i dont have the perfect family, my parents divorce, my dad doesnt really care anymore and my mom calls when it's night already so I'm really upset when my friends didnt give a fuck), since that day (my 21 birthday), I left the group all together (on whatsapp). Before i got angry, almost all of us promised to hang out together but I bailed on them because i was upset, they even called me but i didnt wven picked up (days letter, my friends said that they were goona buy me a cake and surprise me at my office or even to my home but i was already upset so i didnt picked up). Everytime i remember my birthday i all want is to cry, i know maybe you'll called my crybaby or whatever but i cried everytime i remember my biryhday (even now while im writing this). Im sorry this got so long but i dont have anyone i could tell right now :)
