With regard to your egg donor, imho, you may find it helpful to reframe some of that.
In the 1st example, if your designs were art (rather than technical drawings for something to be manufactured), then your egg donor was plain wrong. Patents are irrelevant. You have copyright over your artistic work. Tell your egg donor she doesn't know what she's on about.
2nd example: if your egg donor is 'coercing' you to throw your art out, like threatening you with a knife if you don't, call the cops. Otherwise, remind yourself "I threw my art away because she said something hurtful". You are in control aand again, simply tell your egg donor that she doesn't know what she's talking about.
We often frame situations in our mind in ways that make us feel powerless. "Thanks brain, but that's actually untrue - I do have control."
You have. more control than you give yourself credit for;)
