Welcome to the forums here, fizz!

I think you found the right place for support and to find people who suffer from similar ailments as yourself.
I also have GAD, and have had clinical depression in the past. My anxiety is mostly health based, but I understand feeling anxious all of the time, and being able to do nothing to make it any better.
My anxiety was so bad at times, that I would literally shake and feel like I was going to crawl out of skin. I'm speaking in the past tense, because I truly found a medication that is working wonders for me. It's called Paxil and it's specifically designed for anxiety, not depression. I'm not saying that I never get anxious anymore, but the Paxil has seriously taken the edge off, and I'm able to function somewhat normally in my every day life.
Glad you found a care worker who you like. Just keep being strong and realizing that there is a light at the end of every tunnel, ok? Even though sometimes it doesn't seem so.
Have you seen the chat room connected to this forum? Very nice and supportive people in there with lots of kindness and advice if you need it. It's a wonderful support group, and I'll bet you will enjoy it. Keep posting though and good luck!
