Severe Anxiety/Depression after LSD/Alcohol?

It could be peramanent ... A friend of mine was normal, then he started frequently doing mdma and other drugs... and then one day he started getting panic attacks out of no where..Now he is diagnosed with an anxiety disorder... Ill tell you this..every time you do drugs and you go back to normal, you better count your lucky stars that you are still normal...cause you never know when that next bump or pill will change your brain forever....Thats why im glad i stopped before any of that stuff happened to me..
