My birthday is here and no one cares

I have been feeling this way for some time now, but for this year I seriously can confirm that my family (cousins and all) don’t really care about me or my birthday. For everyone else’s we always have these big parties and celebrations but for me it’s just a pat on the back. Literally. I don’t mean for this post to sound like I’m being selfish or materialistic but it kind of hurts that for 17 years everyone has put me on the back burner and don’t even give me a card. And for my birthday this year, (it’s this Tuesday) my brother that I barely talk too or know asked if I wanted to go to dinner so I am excited to actually do something for once on my birthday and even invited my other sister so I would feel a little comfortable but I don’t even feel like I deserve to do that. Part of me is like “I deserve this, I deserve to have a nice dinner, dress up because I never do anymore and just have fun” but the other part of me feels as if I just don’t deserve to celebrate my birthday because what is there to celebrate? If my family doesn’t care then it’s really just another day. I hate that I feel this way and I don’t know what to do. Please help me.
