Or you can get high: http://www.scientificamerican.com/article.cfm?id=hallucinoge... I've found that the best way to handle anxiety to stop talking about it all the time, and just fill your mind with living . When HN gets in a spate of depression/anxiety discussions, it drags my mental health down. It's almost enough to get me in support of the concept of Trigger Warnings.
Psychedelic experiences and meditation are closely interrelated.
Filling your mind with one thing instead of the other is a temporary solution. It's another form of avoidance.
Anxiety arises from an underlying emotional issue that someone is avoiding.
In the psychedelic and meditative states, it is entirely possible to feel oneness and love for all that is. That's fine. For insight meditators, this is a peak experience that is itself transitory. We'd call this the first "flowering". There is still much work to reach the "fruit".
Think about it. You're given the gift of unity consciousness, of love and light. But, the tendency after that is then select only some of the experience as good, and to reject the rest as bad. The gift of the bliss and love is to teach you what it is like to be unconditionally accepting of all that is.
And unconditionally accepting includes the experiences of anxiety, depression, misery ... It's only when you accept the experiencing that you can become a complete person.
So HN gets in a spate of depression and anxiety discussion. "It drags my mental health down." The practice at this point is to disassociate the apparent cause and effect and focus on what you are experiencing at the moment. "I feel that my focus is breaking apart." "I feel my mood going down." And you go deeper, observing the sensations that make that up: where exactly, in your body, are you feeling it? What color is it? What texture? What temperature? Any sounds, smell, or taste? Then you note it and let it go, go back to focus on living and breathing.
Over time, you gain the ability to mindfully observe anxiety or any other sensation as they pass through your awareness, yet you are not moved. It is in this way, the mystics would call "finding your center". It no longer matters that HN gets in a spate of depression and anxiety discussions. You are OK with that.
