cause you left the frays from the ties you severed when you say "best friends means friends forever"

I know that I have heaps and heaps to be thankful for. So any things in my life are ironing themselves out and 'm making connections with people who were so important for such a long expanse in my life. People I thought I'd never bridge those gaps with again. I love my job, my boss is so fatherly and incredible and the people are like a second family. I miss a day of work and the next day is a mixture of hugs and concerned faces. I just love the stick together-ness of it all, and how fantastic they all make me feel. Sometimes the job itself can get a bit trying, but we're always there to perk eachother up. The people I live with are tenderhearted and loving and my family is as wonderful as ever.
So all things considered, why do I feel so worn down? I have a lot. I have loving friends, giving coworkers, a compassionate family and a merciful God.
I'm healthy and my needs are provided for. I have tons of people looking out for me and willing to do anything for me, and yet it all feels so minute.
Why do I feel like I've lost the world, when I still have so much?
