Yikes! That looks rough!
Are you aware that the 忄radical is a form of heart - 心 ? So you can see that both of the kanji in your list have heart in them, so you could build your own mnemonics focusing on the emotion meaning of the word feeling, and try to build up some sort of emotion in your own heart as you recall the mnemonic. 情 already has emotion listed as a synonym, and I don’t think it would be too off to add emotion as a synonym for 感, if that would help.
