<human>: Can you give me the gist of the text in a nutshell?

So. Today I turned 20. I feel depressed, not sad, just empty.

I originally had planned on just meeting up with one of my best friends, just watch films. (Only her, I don't know why but I am at a point where I both want to reach out to people but feel conflicted and refuse to.) However, I found out fairly last minute she had to attend a wending on the day and cancelled; further she will be working before, and at least 4 days after the event. Other best friend at least contacted me but she's moving house in another city. I didn't make any alternative plans as I was just feeling extremely low that I wouldn't see either of my best friends. 

Further, this morning I realised I had my privacy setting on FB so it didn't show my birthday, I eventually turned it off at around noon, a few people whom I'm not close with then proceeded to wish me a happy birthday. I'm a uni student, and I thought I had made close friends at Uni, but only one or two wished me a happy birthday. The closest group I was with, whom I travelled abroad with and hang out with didn't even seem to notice. 

I'm already in a one sided but I feel justified friendship with one of my best friends, this birthday has just hit me hard and I feel like no one cares.
<bot>: Hi! I'm alone for my birthday, stalking my own fb feeling bad for myself. Super healthy ain't it?
