How to recover, should say start again with courage. But I know this is a cheap answer.
Investigate ourselves and learn to be mindful ourselves, gain some insight in own mind. Since samsara is the tendency to find faults with others, which is just clouding the already confused and so suspicious mind even more, we must investigate own mind and see its limitations. Then when we are ready and honest to ourselves, we can find the genuine teacher and trust.
Then we can easier avoid these.
"Swindlers are worshipped like dieties and gods,
Charlatans are prized more than jewels and gold,
The religious are tossed like pebbles on the road.
How pitiful, ignorant beings".
"beyond 8 worldly concerns the sun of happiness shines". Beyond worldy peace and war.
"Despite the fact that we are a ceaselessly transforming stream, interdependent with other beings and the whole world, we imagine that there exists in us an unchanging entity that characterizes us and that we must protect and please. A thorough analysis of this reveals that it is only a fictitious mental construct".
Shechen Rabjam Rinpoche.
