The most powerful words in the world are the things we tell ourselves and believe.
I went to some workshop my mom really wanted me to attend after my marriage fell apart. It was years ago, and I don't remember much because it really wasn't my thing, but I clearly remember that phrase.
I took that to mean that it starts with how you treat yourself.
As someone who hit rock bottom, it gets better. My marriage ended with me in handcuffs, accused of something I didn't do, with one of my daughters in an ambulance going to a psych hospital and the other daughter with my mom.
The charges got dropped the next day (long story) but I still spent a night in jail, and all I could think about is how long 20 years would be. How old my kids would be. I was 31 at the time.
I'm 35 now, moving in with a woman I couldn't imagine not sharing the rest of my life with. My kids are with me for the school year, and they go stay with my ex for the summer. Literally everyone (even my ex) is better off, even if it doesn't make me happy to admit it.
It gets better. And I think it starts by being nicer to yourself.
Therapy can really help, too.
It should only be concerning if you find you like torturing them, and you start escalating to other animals.
Some early signs of psychopathy are torturing small animals, like cats and squirrels. Something to do with a lack of empathy.
If you can remain content to simply murder slugs and other crawlies that invade your domicile, then you're not a danger to anyone.
