Feeling unappreciated

Hi, so today I turn 21 and while I feel grateful for all the things that I have in life I still feel unappreciated.

So just to give a background, ever since I was little I took care of myself because both my parents used to work. My mom stayed a SAHM until my brother was like 6 or 7 yrs old, It wasn't that in my case (she went to work after two years after I was born).

On to why I'm feeling low, so I feel unappreciated because my family didn't even get a cake for me, we go out to dinners on every occasion. There was no cake, no gifts. I don't expect those things from them anymore but I do everything I can for them, I make sure we cut cakes on their birthday, if I have enough money saved up I get them gifts but to think that they don't do these things for me is not a good feeling.

I asked for one thing to my brother for my birthday and I didn't get that. I kept thinking there's still time for my birthday to and I will get something but all I got was disappointment. So anyways, happy birthday to me, yay!
