I don't do little/age play, but I'm a sub, and that's a different role than I am in professionally or within my family. I can't say that it enables me to face the rest of life, but I think it is a refuge in a way. I can let go of making some decisions and trust my Dom to tell me what to do and look out for me.
When we first got together, I was in a bad place mentally because of an abusive marriage. I didn't care much at all about myself and didn't take care of myself like I should. He valued me, and in making me stop taking chances and start taking better care of myself, I started coming out of the bad state of mind I was in.
I can still slide into it sometimes when something bad happens, and when I make a negative comment about myself, He talks me back up again. He reminds me that the reason I'm thinking that way, usually blaming myself, is because of what my ex did. It's not happening as often as it used to, and I'm even finding that sometimes when I start thinking that way, I can talk myself back up.
He also helps me remember to do stuff that's not part of my ordinary routine, and He holds me responsible if I do something like running through a yellow light. (No, that doesn't happen often anymore!) Plus, we just have fun sometimes, like talking recipes and dogs. I value that friendship because it also helps me in real life even though I'm not in my sub role or mindset at the time.
