Am i overreacting? Or should i say something?

I'm 22 years old i'm in college and i still stay at home. My whole life has been a roller coaster. I've never really had anybody to talk to about my problems because my older sisters are 30+ so they don't understand. I do have 2 younger siblings they are 15 and its like everyone in my family overlooks me and all the attention is on them. On my 22nd bday i didn't get any gift barely got any calls, then my oldest sister comes over with a gift for my yonger siblings.IT'S MY BDAY! Keep in mind. Now my dad isn't in my life but my younger siblings dad is and boy are they lucky he gets them anything they ask for. We all wanted iphones but me on my college budget had to get a job WORK MY AZZ off to get it, they just asked their dad and BAM they got one. I don't know maybe i'm jealous because my whole life has been hell and their living in paradise. It sucks to know that whenever i wanted something i had to work for it but they don't. I'm never the one to complain but when your surrounded by this you don't have a choice. We have pics all around the house of them NONE of me.noone ever mentions me EVER i actually like getting sick becuz thats when i get attention, i went to my aunts house and looked in her picture book everyone was in it but guess who wasn't. ME. And yes ik i'm 22 and a female but i've felt like this ever since they were born, i feel like noone in my family loves me. I'm a really cool person i'm a Leo so i'm pretty laid back so i would never express this to them, somebody please help me.

Well I feel for you because you can't change birth order or the fact that your parents have had multiple marrages But because of this you are in the middle. No family will ever be the Brady Bunch. Just live the best you can and make sure your own kids are not treated as you were.

Maybe you should move out so you don't have to be around them
