<human>: I'm a 20 year old female, who seems to be stuck in a constant state of limbo.

Everything feels mediocre. I feel numb (not just because I had a root canal and can't feel the whole left side of my face), but numb.. I have to fork out a grand for this root canal and I just don't have the money. 

I'm only half dating a guy who has been far too busy with exams and other things to have time for me. 

I have no income, but $300 in my bank account to pay rent etc until I find a job.

I have no friends or family to fall back on.

I want so badly to be happy, but I can't be. I can't get over this constant shadow over my brain. Stopping me from enjoying anything..

Can you give me the gist of the text in a nutshell?
<bot>: I don't know what to do Reddit, how do I get out of this self-pity/depression?
