I’ve only recently had to move out to my new flat.

I’ve been living with a family from one of my friends. Before that, I never really had a place to call my own. My family members are mostly alcoholics and terrible people.
I’m an introvert, and the family I’ve lived with decided it’d be best for me to move out and find a place for myself. For my own sake.
About the accusations:

My sister has been going around spreading lies.
She’s told everyone the reason I got “kicked out” was because I’m a dirty thief.
Apparently I stole something from them.
She even messaged me an entire paragraph on Facebook (we don’t have eachothers numbers) saying how pathetic I am. How I always get what I want and how stealing only proceeds to get me my own flat.
I’ve never stolen in my life. These accusations have seriously tormented me these past days. But she blocked me immediatly after she sent me the message.

She’s 33, but sometimes I wonder who’s more mature. Me, or her?

Now I can’t let anyone of my family see me. What are they thinking of me? But at the same time, I don’t care.
But I kinda do. I don’t want anyone to think badly of me. I’m not a bad person.

I just wonder how my sister got that idea of me stealing.

I haven’t seen or talked to her in months. I’ve only said no when she asked if I could help her out financially a few weeks ago. I had no money myself.

My thoughts are too much.
