Was that at the concert? Or beforehand?

Either way, it doesn't detract away from the rest of my post.

You need to start thinking outside the obsessional one thought you have about trying to be her daughter.

Even if she was your mother, it would still be unhealthy for adult you to be so obsessed with your mother. I mean this in the kindest way but you need to start accepting that it's time to learn to grow up. You can still have all sorts of love, affection and connection, but you can't fixate on one human being, cast them in a surrogate role and make them responsible for your happiness. It would be suffocating for a real mother (who would be desperately worried about you, and no doubt feel they had failed to raise an independent adult) but it must be a massively confusing deal for LC as well. And for you. On some level you know it's not right and there is SO MUCH MORE to you - look how flipping talented you are at music!
