There are two sides to every coin. Some people are just not cut out to be caregivers or part of your support system. They just mentally can't handle it because they may find it draining, anxiety inducing, etc.. So, it is important to remember that her decision reflects herself and her beliefs, not you.

I'm sorry that she blocked you on Facebook and Facebook messenger, though. I think that was a little harsh considering she wanted a "break." However, she might be doing this to protect her own mental health, because she may feel that you are stressful *to her*, and times like these are very stressful on a lot of people. That does NOT mean you are stressful to deal with. That is just HER opinion. Everyone has different levels of stress tolerance, and not everyone is like that, I promise.

I hope you feel better soon. I can only imagine how hurtful this was. But if she is a negative influence on you like your sister says, then maybe we should remember that everything in life happens for a reason, and sometimes as one door closes, another one opens.
