I wish I had better answers for you, Felicity. I know what it is, to have someone expect things of you, even though you're not the person they remember. All I can tell you is to just be true to yourself, however you can.
And maybe that means you need to sit down and have more serious talks with these people, so you can both set up the current situation you both see yourselves in, and come to an understanding. Right now it feels like you're still isolated, but you need to connect. Two systems speaking the same language, but at different rates.
