((Rose)),
I think you just need to have someplace to vent and weigh everything out. Being a caregiver as you have been is very stressful and draining and as you already know, having an outlet where you can get a break from it is very important. I have noticed you are a very loyal and responsible person Rose, my concern has been that you make sure you take care of yourself too.
What is helpful is that you step back and think about what you would advise a woman in your position where you are thinking of that woman's well being and not just the person she is helping. You have always been a kind of caregiver in your life Rose and you have been a person that has always wanted to do it responsibly too. But, you have to make sure that you are also seeing "both" people in this scenario too, which is why you need to step back and consider what you would say to a woman in your situation.
