Hi Shauna
I was browsing the forums and noticed noone had responded to you - I think if you post this as a new post of your own, you will get a response from one of the more regular members.
Having said that, I will also respond here. I get extreme anxiety too. Sometimes it can make you feel weird in various ways, including disconnected and anxious about situations that may normally make you feel safe. Other things that go along with the anxiety may also contribute to your feelings - eg sometimes when I don't sleep well I am not rested enough to deal with things as calmly as I would normally, or sometimes I forget to eat enough and this will also make my brain unable to cope as well as it normally would. This or other things may also be part of your feelings. Your recent relationship breakup may also be contributing as this sounds as if it was traumatic. Everyone needs time to get over relationship breakups, be kind to yourself as you heal from that, and know that for a time you might feel a bit unhinged.
On a more philosophical level :) ..It is totally normal and intelligent to wonder what your life is and what you are doing. Smart people spend their whole lives thinking about these questions and seeking and finding or creating meaning in their lives. It means you have a critical mind. And that can be a hard thing but it is also a good thing.
Panic attacks are common with anxiety also. The best thing to know when you are having one of these is that the feeling will pass. If you have not talked to a counsellor or doctor you might find they are able to help.
As for distractions, I find craft, colouring, things like that can help me. Kind of mindless but slightly creative things :)
