Helping a Family Member

[Leos]

I'm not at the point where I feel remotely comfortable giving anyone advice, making judgements, or teaching people anything. However, recent events involving a family member are compelling me to act on their behalf. I would like to know if there is anything I can/should teach them as an addition to the therapy they are already receiving, which is in essence a support group hosted by a therapist with children his age.

He had a falling out with a former male friend his age who he essentially worshipped and is now exhibiting some paranoid and schizotypal tendencies. To make a long story short, he's in a state of fear and paranoia, believes he's being stalked and monitored in a variety of ways, believes other people are influencing him via subliminal messages, projects the fears he has internally onto other people distorting his perceptions of them, doesn't trust any of his friends or his family, dwells on fearful possibilities so much they become real in his mind, projects impossible levels of power onto other people while himself feeling powerless, and feels like he has "lost" something essential and is on a downward spiral. He doesn't admit it to himself but he's addicted to feeling fear and anxiety and chooses it over other possibilities every time.

He doesn't practice any kind of mental/emotional exercises, so all he does is think and dwell on the issues making them bigger. He doesn't have any belief in a higher power to call on for support or surrender to (atheist currently). I've helped him recognize that he is highly suggestable however when I asked him to dump his fear and anxiety on me and somehow he felt better (which was sneaky and probably irresponsible). I had been his anchor for many years keeping him stable, but am no longer present due to living too far away to give immediate support. He's expressed paranoid and even suicidal ideations so I cannot take this lightly.

Would a form of the grounding exercise (tree version perhaps) help him at this age? I'm not sure of the correct age.
Given his impossible projections of power onto other people and a feeling of losing an essential part of himself, would a soul retrieval meditation help?
I realize he's coming of age where he must make his own decisions and be responsible for himself, but I still feel my help is needed. Is there anything that can be done?

Forgot to mention, he is a 15 year old male in high school.

  FST is not healer training... though there are exceptions for vampires. I think what you are really asking... Yes you can ask your vortex to help him. It handles consent issues in its own way.
