Hi Spartan,
I have been in a very similar situation as you, just a few months ago! I also have a feeling I should take my own advice that I'm about to give you :) So this is good for me, too.
Just because you had a harder day don't let it keep you from being proud of the two days you did well. Two 8 hour work days WAS a big success! Moving away from home and working many days in a row of your job was maybe just too much right now. That doesn't mean you've failed - it just means that maybe you're asking too much of yourself right now. Maybe you need to give yourself a little bit of a break and tackle one thing at a time. For me, I moved away from home in April and started my job up again, and after a few months I recognized that it was too much. I have stopped my job for now, which wasn't right for me anymore for many reasons, and I am focusing on working through my anxiety and also on other things that are important to me like my photography career.
I'll ask Ashley's question again - what is it about home that you miss? For me it was my connection to my parents, so I talked to them on the phone every day for a while, and still talk to them often. That helps me feel like I'm still connected to them and supported by them even though now I go weeks or months without seeing them.
I was really skeptical when I started this program, too. I started it once last December, then stopped for a while, but came back to it in July and am giving it 100% effort this time. I still have a long ways to go, but I've found that if you really do the homework it does help. It can be frustrating because you just want to "get better", but it is a long and sometimes bumpy road. There will be setbacks/rebounds, but that doesn't mean you aren't making any progress. Post here with both your ups and your downs and before long it will be obvious that you're heading in the right direction.
Just know that you're definitely not alone, and that there is a way out of this - you won't be stuck forever!
