Eastercon advice

I would really like to go to Eastercon this year, but anxiety brain is making me second and third guess myself about my ability to deal with the full con experience. I know I’ve done three years of Nine Worlds, but the central London location made it really easy to stay off site and for T to come too and just go off and do his own thing during the days; that’s not going to work for Eastercon so it would just be me by myself and I’m a bit worried about how that would go. (It doesn’t help that Easter is so late this year I won’t be able to take recovery time the week after, as it’s 0th week of term and work will be busy.)

Reassurances, encouragement and stories of how to survive a con as the kind of sociable introvert who absolutely loves the right kind of interactions with people right up to the point where she goes splat and tends not to be great at pacing would be appreciated here!
