I see what you mean now when you say I'm CHEAP, merika

Luba, I've felt like that at times when I've struggled to cope with the demands others have made of me, particularly when I was younger. Now I find it much easier to set boundaries that mean I give what I can, when I can. Think of it this way. You are a positive influence in her life and can only remain so if you don't get too affected by her problems. So help as much as you can, but know that you are doing the right thing for both of you if you occasionally need to withdraw to restore the bit of you that's helping her.
Non-jugmental is fine but do encourage her to look at things from alternative perspectives and to persist in seeking treatment that helps. Just don't expect her to take on board everything you say. The meds should be helping if she's been on them for more than 2 weeks, if they aren't she should go back to her Doctor. It sometimes takes a while to get the right diagnosis as well as the type and dosage of meds. The right type of therapy with someone she can relate well to may help too. Her doctor is the best person to advise on the type. I think cognitive behavioural psychotherapy works well for depression. There's a strong research base to prove it's effectiveness.
