Unhappy and Angry All the Time: Is It Depression or Anxiety?

What you're describing sounds a lot like depression — and the anger you feel is part of it, not proof that you're a bad person. Depression doesn't always look like lying in bed crying. In a culture like ours, where it's hard to say "I'm sad" without feeling judged, it often comes out as constant irritability, snapping at small things, and feeling like everyone around you is the problem. When there's that much pain underneath, the smallest thing sets you off.

That is also why it's ruining your relationships. Anger is a mask — underneath it there's usually hurt, exhaustion, or fear, and the people close to you only ever see the mask. They respond to your anger as if it's all of you, and you both end up hurt. It could also be anxiety mixed in; anxious people live on edge, and living on edge makes anyone short-tempered. The exact label matters less than you think.

What matters is that this is treatable, and many people in Pakistan feel exactly what you're feeling and never say it out loud. You already said it out loud, which is more than most people manage.
