I think as long as you are assertive about it, telling your SW those things is completely fair. I have a SW who can be forgetful and unhelpful at times, and I find that being honest about it is good and she agrees. Every time we have worked our way forward from whatever difficulty has come up and our working relationship or whatever you want to call it is a lot stronger for it.
I would try and have a think about what you would expect from her and how you want things to be different, as this is something she may raise with you.
As a SW she should want to help you, so I don't think it does any harm to let her know how you feel. If I was her I would rather know what I'm doing wrong so I can trying and change it, than you continue to hold your feelings in and me not be able to help you.
