Hey.

the title says it all.
I've been training my brain to cope with (sometimes crippling) anxiety and excessive worrying for years. Since about 15 and am 30 now. Ups and downs. Bad periods and worse periods. I am exhausted everyday by actively correcting my thought flow and manage this OCD-like form of overthinking and overanalysing thoughts. I get very stressed and paranoid, daily. 
In absolute unbearable situations I would take 500mg of phenibut or a 0.5mg Xanax. Very rarely! As I am very afraid it will lose its effect if I use it regularly and it's my only safety net.
However, I have come to the conclusion it is the only way to feel like myself. Normal, stable. Calm. And I wish to be this person and enjoy my life again.

Its not that I want to give up trying to fight this naturally. But when is it time to admit I can't do this on my own any longer? 

I do see a therapist since about 6 months but I'm not sure how to start this conversation with her, as we are now in the midst of CBT. I'm also afraid of what they would subscribe me in terms of side effects and addiction.

Maybe any of you are of have been in this situation before and could give me a word of advice?

Thanks.
