2. Constantly Irritable
Source: http://www.thesuccessfulgrownup.com
People that suffer from depression can become constantly irritable. Even when the situation doesn’t call for such a strong reaction or even any type of annoyance or impatience, yet they end up being massively angry, it could be due to depression. Even simple things can cause them to behave horribly, even when the events don’t necessarily deserve any harsh criticism or mean behavior. If you notice reactions like this, then depression could actually be the reason behind it.
