19F is it bad wanting to be alone most of the time

I’m easy to get along with, but I often need my own time. Having that space for myself has caused me to lose some friends because they think I’m being fake or not true to them. The truth is, I’ve always been real and kind to everyone. It’s just that sometimes, I enjoy being alone and recharging in peace. I guess not everyone understands that needing space doesn’t mean I care any less ... it just means I’m learning to value my peace as much as I value my friendships. I don't want to lose them but I can't also stop myself wanting to be alone... siiighh
