SIrB don't be embarrassed. Everyone finds these things complicated and confusing (I think they do it deliberately). It sounds like you are entitled to a lot more than you are claiming though. That money DP gives is for Bryn, not you, so I'm sure it shouldn't effect your personal entitlements.
Why not contact one of these local groups so someone can go through it all with you in person?
