Words can't explain how I feel.

My son is fixing to be 3. I've only been working like 2 months. But I've always had him with me and I'm feeling depressed about it. On top of that I hate my job and everyone's so rude and have bad attitudes. I don't feel like I spend enough times with the ones I love including my son, family, & my SO! I stress myself and worry myself on the days I know I have to work. Night shift blows.. I also feel like just quitting and giving up. I don't know what to do.. I think I have an anxiety / depression disorder..
