Look, for the future, you need to understand this is totally your fault. While your employer is happy they managed to squeeze out a raise for you (maybore more than other people got) and thinks you should be grateful you put a message on here basically showing your frustration.
Im not saying this to upset you, but to educate you and other readers why it is your fault.
You have to be responsible for yourself, now and in the future. That means you have to set expectations before a review and lay out justification for why your expectations should be met and potential consequences if they are not.
Now the simplest form of this is "hey boss, I work hard and deserve $2 more per hour and if I dont get that Im quitting" - unfortunately that will get you fired.
Instead you have to be subtle, but direct whilst also kissing ass - something like this will often work "hey boss, I love working here. I've just got my degree and I have been putting in 60 hour weeks for the last couple of months, but I need to make more money. I feel with the additional work I have been doing and my improvements in education, including the fact that I have <xxx - something here to show improvements in profit for the company> means I should be earning $16 per hour instead of $13 per hour that I am on now. I hope you can look at this in my review that is due next month. Like I said, I love it here and dont want to have to leave just to get more money so I hope you can give this some consideration".
See how you start nice and end nice. How you try to justify the raise, which could be any of the following:
There are still some employers who wont give you the raise so if thats the case look elsewhere for a job and then quit (dont quit before yo have another offer). I would say 75% of employers are great and 25% are not good, so understand if you got unlucky and work for a not-so-great firm, your new job may be much better.
