Update:

Well, I received a reduced hours sick note and will be working 8-1 for the next 2 weeks. Went down ok at work (at least that was the impression given) and I'm going to try and make the best of the down time to get some balance back. Actually feeling less overwhelmed over the last couple of days... intrusive thoughts/voices are still there but I'm not being effected as hard by them so going to see that as an improvement.

Medication has been upped and I take the first tab tonight so hopefully it won't disrupt me too much.
