Have you tried having an "anxiety-moment"? During the day, write down everything that bugs you or keeps your mind in a bad mood. Remind yourself that you don't have to think about it at that moment - there will be time later.
When you feel ready (or perhaps not) take half an hour to sit down and have your "anxiety-moment". Choose a spot where you normally don't sit, like in the corner of a room or something. Now is the time to let your mind wander: worry or just allow every feeling you have to take its place in your body. Everything is alright and it's nothing to be afraid of. You could also write freely what you think about. When the half an hour is up, do something else. If anything comes up - write it down and "save" it to the next moment. A half an hour a day isn't much precious time going to waste.
You could also structure your "anxiety-moment", by dividing the worries into things that can be changed, and things that can't. Make a plan for the changeable stuff. The other things can't be changed anyway - so why bother?
Don't know if this could be relevant to you but this has helped me work with myself. Also mediating... have you tried that?
And remember: "Yes, I suffer. But that doesn't mean that something is fundamentally wrong."
We're here for you!
Hugs!
