I would personally not file with the EEOC in this situation and just try to find other employment when you feel able to work. It sounds like you were unreliable at your job from June-July, and over a month of poor performance is a perfectly valid reason to let you go. Also the fact that you used Facebook at work makes you look bad, as well as telling your co-workers that you'd wish they'd fire you. I know you were likely saying that out of frustration but it still doesn't look good on you.

I used to have issues with being reliable at work when feeling depressed, and I could definitely understand the perspectives of my employer. It's important for employees to be reliable, show up on time and stay the whole shift while carrying their weight in work. If you feel unable to do this, it might be time to take a small break to focus on your mental health or even file for disability if you think this will last for a while. When your mood is better and you are able to be reliable at work, that is when you should be working.
