If you have an active eating disorder, and are concerned it's flaring up then that's a good reason to seek help in my opinion. As bizi said, you know yourself best. EDs are tricky, they try to lie and tell us we're not bad enough off and should give into them more. Also, I get how confusing it can be when people say you seem well when you are not, that happened to me before when I was mentally unwell last year. Other people aren't in our minds and bodies and so we know best, though.
You deserve help, and I hope your therapist turns out to be a great fit and can help you with this and anything else you need to work on. EDs are problems regardless of the numbers and whether or not everyone can see the problem right away. Please take care!
