Indeed leaping to unevidenced assumptions is all you need, using an argumentum ad ignorantiam fallacy. Nothing is lent credence because of a lack of contrary evidence or explanation, so unevidenced assumption here is irrational by definition. I look forward to you not addressing this point at all, while pretending you’re after discussion rather than simply preaching your beliefs.
BS, I don’t believe you presented that claim to a qualified mental health professional in good standing, and they said it was not an issue, you’re lying.
