Ok, you might need another approach.
Keep using SLR 3.0 and blockages removers a bit.
Then add Mana circuits, use the ‘Energy expansion’ card
Then get the heart chakra field and try to develop your heart chakra, lots of that is related to Heart chakra.
And also, try sometimes conscious interactions, meditations with fields and see.
This may take long, but with long continuous practise, it should deliver.
From what I understand, you are quite young. Young system may initially not be responsive that much, but that’s just my observation.
