There's a poem by Rupi Kaur that goes, “loneliness is a sign you are in desperate need of yourself.” 

I read this and it really changed how I viewed my life these past few months.

I realised that if literally anyone was to leave me I'd be fine, because I got me. I’m so caught up in my future goals and my progress that I don’t have time for people stepping in and out of my life. I’m really all I ever needed anyways, and being lonely just isn’t something that applies to me anymore. My fear of abandonment has really decayed and I’m so grateful for that.
