I know the feeling well mate. I have had anxiety for 8 years, nightmare is the only word that comes to mind!
what anti-d's were you on? If you have lowered the dose a few months ago it should have kicken in any sides as in anxiety within the first 7 days. Some can take longer though. Citalopram can take a good few weeks to show its effects after reduction.
Do you have any Valium? Diazepam, Lorezepam, Tamazepam etc all help. They are addictive but to no way to the extent people make out. Some Anabolic Steroids can worsen anxiety. Thai anabol really fucked me up with my anxiety, big shame as the results were fantastic. The more Anabolic the better so I have read and been told, keep clear of the Androgenic, although Sust has had good results in helping anxiety, again this is what I have been told.
