Seven 10-day and one 20-day Goenka Course but no "good results"
I would suggest you try another vipassana lineage. Goenka goes for body sensations only (AFAIK, later they add mind objects, but I only have 2nd-hand knowledge about it). Use a technique where all 4 foundations (body, feelings, mind, mind objects) are used from the very start could be useful; I am personally doing Chomtong-style practice (Ajahn Tong, a variant of Mahasi, dry-vipassana with lower concentration) and being exposed to e.g. difficult feelings and learn to acknowledge them and let go is extremely valuable for me. What I also find very useful is to have regular interviews with teacher on the retreat.

Meditation has good results if you have more clarity, understanding or yourself and others etc; in short, if your life is better. Experiences come and go and have little long-term relevance (despite the mind trying to persuade us this is it in that moment).
