When I was new here I used to have an anxiety thing too, and I totally cured this just by doing the meditations and RTRs. I tried marijuana a few times for the same reason as you. In the moment it felt like it temporarily relieved some anxiety and depression, but over time it actually made them much worse. Marijiana is only a way of covering up and ignoring these problems. The comfort comes because you won't think about the problems if you're all fuzzy. And all the time that you're covering up the source of the problems in this way, they are actually getting steadily worse. The only way to actually solve problems like anxiety and depression is to find out what the cause is and to fix the root of the problem.
Anxiety and depression are caused usually by two things. It's a mix of low life-force energy and bad habits in the thinking. Habits of thinking negatively act as an affirmation to empower even more negative thinking. It's a feedback loop of amplifying negativity that just keeps growing. Then it drags in all other kinds of negativity and makes the whole life worse in many ways. The only way out of this is to keep control of your thoughts and not let them be negative anymore. Thoughts are affirmations which program energy to do what you are thinking. You need to watch all your thoughts and keep them positive. And at the same time do meditations and RTR to increase the life-force of your soul and clean out all the garbage. The meditations and RTR will bring you up to a level where you just don't have any of that negativity anymore. And positive thoughts keep you going in the right direction. This is how I helped myself.
Another thing about marijuana is it prys open the subconscious mind to be influenced and controled. This is why 100% of the "entertainment" directed at smokers is designed to make them retarded and fill them with all kinds of hang ups. So somebody surrounded by bad influences who smokes ends up invoking and growing into these bad influences, and these bad influences are all around. So being sober is that much more careful that it's less likely for you to be influenced and controled in that way.
And most of the "positive" effects of marijuana are just bad imitations of what you can gain for real with spiritual practices. That fuzzy buzzing in your body, you can get this for real by doing kundalini yoga. If you do kundalini yoga fast enough, your whole body will be so full of this life-force energy buzzing through you you'll be amazed how you can even hold it together. And all of this is making you permanently stronger. Marijuana can't do this, all it does is have chemicals bind to "spiritual nerves" to falsely feel like there is some sort of spiritual power being felt, but there isn't any real power it's just a fake chemical imitation of spirituality.
Another thing is opening your pineal gland is the real natural healthy way to feel high. I spent a long time one day working on my pineal gland, and for almost a week after it felt like I was high but I was 100% sober.
This is why marijuana is targeted so strongly toward gentiles. They have been kept away from true spirituality for so many lifetimes their souls are desperately starving for spiritual growth and cleaning. So they are given a worthless and harmful imitation of spiritual feelings, and they are told that this is what is healthy and natural for them. And they don't know any better, it's a distraction from actual spirituality so they stay on the same worthless stagnant path. But they are so spiritually desperate that they take this in because at least it feels like it could be something.
Just do yoga, work on your chakras, do the meditations and RTR, and keep your thoughts positive. You don't need marijuana it's fake and just gets in the way.
