Today is my birthday and I feel lonelier than ever

So today is my birthday and I haven’t felt so depressed in a long time and today just had to be the day it hit. My boyfriend forgot about my birthday, “friends” who I’ve been friends w for years are changing drastically and I’m constantly basing after them even though I know I shouldn’t. Its not about people forgetting my birthday, I guess I just miss them a lot and I feel very lonely. I’ve invited a few people over for a really small party, and I guess I have that to look forward to. But this just makes me wonder if people even care? I sound selfish and I’m just rambling but I have no one to tell this to. I’ve felt lonely for the past 2 years and I suffer from major social anxiety. So it’s really hard for me to make friends. I guess I might be over exaggerating but I can physically feel the sadness in my chest. If anyone is reading this thank u for listening.
