Be passionate, be angry. Yell, cry, scream, curse, throw things. Throw a tantrum. When did throwing tantrums become childish? Grown folks have them, too. Get it out. Regret nothing, and regret none of these emotions, but also learn to let it go or it will poison you. But understand that it’s okay to feel these things. It’s okay to get mad, and if someone tells you getting angry is unhealthy, or looks at you funny for having a moment of weakness and throwing a tantrum, put your entire foot in their ass and tell them to go fuck themselves. And then move on, let go, and love… most importantly love yourself.
