GAD 17/21 ... Covid lockdown imprisonment + collateral damage

I have never before Covid, had psychological issues before, but have had to seek the help of the local mental health support team, via my workplace councillor. I have had an assessment, and score 17/21 on the GAD scale, but now am in a 2...6 months waiting list for CBT. My issues are, that personal liberty is something that has always been important to me as a value, and I feel it's been stolen, and that I am serving a prison sentence, with lockdowns "house arrest", denial of social contact etc.... I literally feel I am imprisoned, and I have entrapped nightmares trashing my sleep, over half the nights. In addition to this, I have lost a freind to lockdown suicide, and attended the funeral, and have TWO more freinds on and off threatening the same! (I'm NOT considering it myself) Also, I have found out another freind has cancer, which would have a higher predicted survival rate, had his diagnosis and treatment not been delayed by Covid. At the same time I've had medical tests for an underlying condition, and had to kick the formal complaints service, to get MRI results after 14 weeks, when 1 week was promised. (I'll need surgery, but they want to postpone, until I become an emergency again, to rectify the underlying issue) I want my liberty back, and I'm close to the point of refusing to comply to lockdown to get it back by force!
