Maybe he is experiencing a psychological withdrawal from always being high? Maybe things will improve as he learns to feel again. If he lets himself.
Personally I have had both severe depression and still fight anxiety every day and tried pot at 19 a few times. I felt scared on it as it gave me a dreamlike sensation and made me paranoid. I think people with these challenges will only harm themselves by messing with pot.
I've taken an antidepressant for decades and I feel just like my normal self only I don't get debilitating depression. I also haven't lost my motivation, which pot does...it robs you of motivation. That to me makes it a useless "medicinal" drug. You need your motivation to survive.
I hope your son stays clean and finds a sober way of dealing with uncomfortable feelings. Certain therapy like, cogniitive or dialectical behavioral therapy really help me manage my anxiety day to day. And meditation, which you can get help with by going to YouTube and searching for guided meditation, is far more helpful than pot too. What type of therapy does your sons therapist do? Plain talking therapy did not help me at first, not until my depression was better and my anxiety was under control. I needed to be taught how to relax ,not just talk about my life...just talking with therapist about Life often turns into a quantity party, but does not teach the patient how to challenge his thinking patterns. This is especially important with anxiety. Depression, if bad enough, is often clinically based and can last indefinitely without medical treatment, but I don't think pot ever did anything for depression other than making the person too spaced out to care that he or she is depressed.
