How to dissolve attachments (to a thing or outcome, etc)?

I’ve already searched and didn’t find anything that was useful for my situation.

I understand dissolving attachments is part of inner/shadow work. But a situation has arisen where I need to dissolve an attachment for my own good, to enable me to move onto better things.

I can’t work with Belial right now. Are there any other suitable demons or gods/goddesses? Would Lucifer be a good being to work with for the job?

BTW, I don’t usually work with angels, certainly not the archangels.

TIA for suggestions.
