For 20 years! I have PTSD + Anxiety and I have tried so many medications and therapy however, I am still the same!!

Since I am a Korean I dont have access to THC or medical Weed! 

Shall I move to Thailand? (Legalized) 

Does THC helps my PTSD ish anxiety? 
I want to end this horrible feelings! 

Please any tips? Shall I try THC?
