Who can I turn to

Maybe that's a silly suggestion, but have you told the support worker him/herself? Maybe you have done it already and it made no difference, but otherwise, if you don't find it completely impossible to do, it may be more effective than complaining, at least if you tell them that you feel they are doing this and it upsets you, rather than accusing them of doing it straightaway (even if you are right).

I'm finding it very difficult to look at people when things aren't going well, anyone, regardless what they look like. Somehow seeing their expressions makes the negative feelings they have about me or something/someone else even more overwhelming, so not looking at them reduces this - which means I do miss some of their reactions and the same will also happen to your support worker - not good really. So guess in a way it is your right to ask for them to look at you, on the other hand that isn't easy to enforce and will not be of a good quality anyway if it is enforced. Of course it's totally your right not to be disadvantaged because of a disfigurement or disability or whatever, but not sure if it's really going to help that much to complain to someone a lot higher up about this to start with (unless you have already tried to discuss it with the support worker themselves). Guess if it was only this one person who doesn't look at you it would perhaps irritate you a bit but not that much more, you would just think that person is a bit strange. But you've probably experienced the same with others before, so that makes it a lot worse that even someone who is used to "imperfect" people looks down. Seems important to change it somehow because it's not just impolite of them or making their job more difficult but it's also causing harm to you, but I think it would be more effective to sort it with the person concerned, also for yourself because being able to address it directly may also be a good thing in future. Maybe someone (not the outreach manager who isn't bothered) can give you some advice how to approach this (possibly again)? If you face them they have to face you, quite literally!
