Depression is real. I didn't want to admit it

My husband and I have been together 10 years. On the outside looking in, we have the perfect life. The home, cars, kids, and nice jobs. But in reality, I am unhappy and depressed. I work 40+ hours a week and working on my Master's degree. I cook 4 out 7 nights a week, clean, do laundry, and still try to find time to spend time with my family. I am mentally, physically, and emotionally exhausted. I want to drop out of school, but I have 2 semesters left. Some days I don't know if I'm coming or going. I'm tired. I feel like my husband and I barely spend time together. Just feels like I don't have time. Some days I want to leave because I feel like he deserves better than me. I feel like I'm angry all of the time and usually takes it out on him.

I am literally depressed and no one knows. I have no one to talk to because my friends and coworkers alway sees me happy and laughing at everything, when really I just want to crawl in a hole and be alone. I'm just tired and don't know what to do. I feel like one of these days I'm going to have a mental breakdown and completely shutdown.
