I have no idea where your fear comes from, I know I hated being alone because I didn't like myself much (if at all) in the past.
Since I've learned to like and even love myself, not only do I not mind being alone, I'm more self-assured and don't allow people to emotionally short change me anymore.
I know my worth now.
Just need to remind myself of it sometimes, I'm a work in progress.

Ps. If there are 2 images I apologize, I can never remember how to attach an image with Tapatalk...
