Interesting replies, guys, thanks.
A little more info for you. She is a Christian and is very involved in ministry and teaches childrens church, does missions work, volunteers for ministry organisations, I know she loves the Lord.
The problem I think stems from her past. She was sexually abused when she was younger, and then got very ill. She was very lucky survive when illness struck, and now she has slight, permanent brain injury which affects some of her congnitive abilities. She is no longer able to work, and has to depend on a disability payment to live, and has many other physical issues as a result.
This happened to her in her twenties, so obviously she feels like she got a crummy deal, and she did! She suffers a little from depression too as a result of all of this. When I first noticed her negativity, it was usually more about her life, and how it sucked, and how she couldnt do the things she wanted to do etc. (and I can understand her frustration), but it has slowly morphed into just a general negativity about life and everything in it. We could talk about ANYTHING, and she'll have something negative to say about it. It's depressing!
My struggle is that I don't want to abandon her, as I know she struggles with loneliness. She has just turned 40 and has physical conditions one her age should never have, and is single and is generally unwell. I want to be there for her as a friend, but I'm finding it hard to support her. She never seems to want to look at the positives in life, but rather seems intent on focusing on the crummy things.
It makes me want to scream. I mean, I'm going through a pretty crummy time myself right now, and I could use some support too, and she is not at all edifying or uplifting to be around.
I don't want to talk to her and tell her my feelings, as I know she already has low self esteem, and thinks the world hates her, so I don't think she'd take it well... but I don't know what else to do? I can't ignore her. Do I limit my time with her? What if she starts asking why? What if I GENUINELY have no reason why I can't spend time with her when she asks, I can't make excuses...It's a dilemma!
