hi all, I have been dealing with GAD for about a year and a half now, i have been on Citalopram for that whole duration also which has helped massively and most of the time the intrusive thoughts I can deal with, however over the past week I have had physical sensations which lead to negative recurring thoughts, and I have really struggled to shake off this constant stream of doubt which feels like it is crawling through my skin and around my body. I do headspace whenever I feel like this and it normally works but it is not having the same positive effect, any suggestions? thanks.
