<human>: Can you give me the gist of the text in a nutshell?

So I've been suffering from bouts of depression and anxiety for a couple of years now and I have a really fucking horrible habit of occasionally just going completely AWOL on all my friends for a few a days at a time. Well in the past, I always got back to people within three days. This time is different.

The beginning of March I had to deal with an emergency and had to fly back home (on the other side of the world from where I go to school) and after that fell into a really poisonous trap of self-loathing and apathy. In this process I turned off my phone and it hasn't been on for three weeks. I feel fucking terrible. My friends are probably really worried and really *pissed* (I know I would be) and I've never gone this long without talking to anyone.

It's just that I can't face the prospect of having to explain to many people the same story of what circumstances led me to flying back home randomly. I don't have a good reason for cutting off contact other than the fact that I was really depressed and couldn't bring myself to talk to anyone (other than my parents). Ugghghghhgh. I'm scared to face their anger and questions, I'm scared they won't forgive me, I'm scared of everything. 

Well it's been three weeks and some of my friends even asked my parents if they could ask me to get in touch with them... because now the anxiety has worsened knowing that I will have to deal with their anger as well as explain the same story over and over to different people.

How can I get the courage to talk to them? What's the best (most tactful and sincere) way to reach out and apologize to them? I feel really bad, I really do. I have know some of the greatest people of all time and it's due to my lack of mental stability that's dangerously shutting them out of my life.
<bot>: Completely cut contact with all friends for three weeks, now I'm scared to face them even though I want to reach out to them again. Any advice would be nice :(
