I am pinning my hopes on it being just the mental "illness" that she will pull through.
I've got to try and be there for her at the time she needs me the most, despite the fact she's doing everything in her power to throw it all down the drain.
She's not seeing anyone else at least, she's just gone into self destruct.
Going to be a **** Christmas is all I can say at the moment.
There's no 'pulling through' proper mental illness - after almost 10 years with a girl with a proper mental health condition I can clarify with absolute certainty -
it is not going to go away.
True, there will be times when things are better, but these will always be tempered with the dark side lurking around every corner.
If, as you said before, she has been taking proper medication long term in the past, this is something that is
not going to go away. There will be times when it is in remission, but it always comes back.
I understand your thoughts about being there for her. I've been there and done that. In my case it made FA difference. The sad truth of mental illness is that you cannot help people to get better.
They have to want it for themselves. You can try and try and try but all it will do is wear yourself out. You know the old adage 'you can lead a horse to water but you cannot make it drink'? apply this in spades to mental health issues.
Most people who are suffering a mental health disorder become very self absorbed to the point of selfishness - part of this is the condition and part of it is the medication.
Either way if you have strong feelings for this woman, you are going to end up feeling hurt, confused and isolated from someone who should be as into you as you are of them.
Best advice I can give to you if you want to keep seeing her is to let her come to you if and when she wants to. Do not make the mistake of chasing after her like a carer with 'benefits' (I didn't put that very well). Do your own thing and focus on that. Enjoy what time is good with her, but keep your head on straight regarding the situation and the reality of what is happening.
