Am I just overreacting or should I feel this way?
 

Here is the situation. I had a bday party that I wasn't expecting to have. My friend asked me if I was doing anything for my bday. I said no. So my friend said let me plan one for you. I said okay. My friend asked me what restaurant I want and I said an American restaurant. Well my friend ended up picking an asian restaurant that I ate at before and thought the food was decent. My friend liked this restaurant and thought that I liked it(even though I did say it was decent when I ate with her like a year ago). I didn't speak up and say I didn't really like it because she is planning it after all so I didn't want to make it such a big deal. After dinner there she planned for everyone to go to d&b so we can drink and play games. She brought one guest that I don't know but was fine with me. Later she called her other friends that were around that area that she has not seen in 2 years to hang out with so she ended up splitting her time with her friends and my friends. I guess I feel that she set this bday plan for me at her own convenience and that she didn't value my bday like she should have. We have been pretty close friends and iono I just felt like wtf... Should I feel this way?

Your friend was nice enough to call up all your other friends and get you out of your house on your birthday, so why is it a big deal that she spent some time with friends she hadn't seen in over two years? You had other friends there to hang out with, so it's not like she left you alone on your birthday. She could have left early to go hang out with her other friends, but she stuck around and hung out with both her friends and your friends, so get over it.

Also, fuck the "she didn't value my birthday" bullshit. What do you want her to do, make it a national holiday?

As you get older, your number of friends will somewhat lower down to a certain number of people who can be your true friends, and then there will be a massive amount of just everyday acquaintances. With that said, I think it was cool your friend did that and planned out your whole day and did everything that she could. I mean you must have gotten some sort of gift that made you smile right? Also happy Belated birthday.
