It takes work to be able to turn those emotions back on. Maybe thinking about something that made you angry is one step closer to turning them on again?

Though I can relate to feelings like that meaning vulnerability. For the longest time I refused to allow myself to feel anger or sadness. I numbed everything out. I'm just now learning what anger feels like, and what situations should illicit anger in me. I find it much easier to be angry on behalf of someone else though. It still takes me a long while to identify and be ok with anger relating to myself (abuse, etc)
