Too Much False Thinking
You found the right path but should seek a better guide.
In order to get a great Good Knowing Adviser, you need to plant a lot of blessings just like one must pay more for a better degree from a superior university.
Therefore if I were you, I would concentrate on going to a Mahayana temple to do volunteer work and to make offerings to plant these blessings. In time, because of your sincere effort, you will come across an appropriate Good Knowing Adviser who will be able to guide you. Give it a few years before you again participate in those Dharma Assemblies.
