Depression is being surrounded by people and feeling alone. Sadness is finding out your not invited to the wedding for two of your oldest friends because you share a house with thier ex, the only place you could afford to live. This is the third time in 10 years. I remained friends with the enemy & now I'm not welcome. This person never did me wrong, never treated me badly, never stopped being my friend. Yet now we are the villains, the ones who never cheated or lied. Oh well, that's life.
