Self Worth

I'm so tired of people doubting their self-worth. Last year or so one of my Tumblr followers committed suicide, and that left me heartbroken for quite a while because I had become close with him even though he merely followed my blog and would make silly comments and such. But this past weekend someone who I can physically see, touch, and talk to attempted suicide herself this past weekend. Depression is a mental illness whether people believe it or not and it's taxing to know that someone close to you has it and you can do nothing. I spent an entire night out in the woods with the police looking for her and now though they found her in time and got her medical help, I still feel completely helpless. I'm tired of mending broken parts for other people when they're just going to turn around and break themselves more and more. It's like a never-ending cycle and I can't help them anymore than I already have. The big factor is that they need to want to help themselves too...and she doesn't. Yet I can't abandon her- she's my friend and she considers me one of her closest friends as well, which is why I think it's so hard to understand why she can't see her own self-worth when she's cherished by not just me but everyone that knows her.
