Depressed or just stressed?

I have tension in my neck and head on and off since Nov. All of my tests came back neg. Im starting massage therapy to relieve the stress. However, Ive noticed that I barely like going out and Ive been kind of down in the slums lately. I have a great career a nice house and car but not currently dating. Not so happy about my weight. And I have on an off anxiety. However, I can function, clean, work, I make myself go out, and I hang around fam. Even though I dont really want to go out, I make myself. Is this depression or am I just stressed? (also I drive an hour and a half to work and back plus I do overtime. By the time I get home Im tired so I can barely do anything)
