Jmo79,
I'm sorry to hear about your bf's father. As scary as it may be, these things to happen, and it's all a part of life. It's totally normal to be affraid, however, there are usually many other things that scare us in our daily lives that we simple stuff... in hopes that they will just go away.
When something dramatic happens, the lid starts to come off, and all these feelings that you did not know you had start pouring out out of nowhere.
You mentioned that you feel disconnected from your self and your environment.
What you're going through is actually what alot of people in the US are going through. We are not really taught to deal with our emotions. Our lifestyle is totally un-natural, we are isolated from people, from nature, from the earth. We are bombarded with stimulation, and constantly told that we need to do more, be more, consume more, when none of that is true.
As a result, most people just want to take a pill and forget their problems. This is neither realistic, nor helpfull.
Before seeking medical answers to your questions, I would recommend to talk to people that you trust about the things that are going on in your life.
Try to talk to the people you love, and you may be surprised how common it is to feel overwhelmed these days.
You're not alone, and life does get better.
All the best,
-Daniel
