I like to act out my thoughts and say them out loud
I developed this habit as a teenager. I'm 24 now but over the years it's become so bad that people notice and my friend had to tell me about it. I like to entertain myself by imagining real life scenarios and acting them out and talking out loud too. I know it has a lot to with my depression so by imagining real life scenarios that make me feel happy it's makes me feel better(otherwise I wouldn't do it). I can create a false sense of happiness by doing this all the time. It's so habitual that I wander off in my thoughts when I'm around people and they notice it. It's so hard to break this habit because it makes me feel happy but it effects my social life at the same time. I'm just happier in my thoughts than in real life, sadly.
