I'm with Doe artlady. I know you want what's best for her, but I had a fussy baby that only slept in 5 minute incraments and ate constantly. This went on for months! I was miserable, lonely, frustrated and tried to give him to the garbage man one day I was so out of it. Lack of sleep, isolation, anxiety....drove me to it. Seriously, the garbage man looked at me and said, "Mam', we can't take that." I truly did and I wouldn't have really did it, but I was going over the edge. I would call my Mom crying, venting, mad at my DH because he wasn't helping....etc. She was my only contact with the outside world because I didn't have time to talk to friends on the phone or visit....I was busy and I knew Mom would be supportive. It was isolation, but it was self-imposed isolation because I was at my wit's end. It eventually straightened out, but boy was that a rough time for me. I was always outgoing and became a hermit during that time, luckily for everyone else, because I was not fit company and probably would have bit everyone's head off for nothing.
Just keep that in mind. She probably sees you as her safe haven to talk to right now, with no reprecussions. The best thing my Mom did for me was to listen, but not help much in the beginning. She would have in a heartbeat if I would have asked, but she knew I needed to learn too. She would come by and drop off a casserole, stay for just a bit and leave. When she could tell I was about to lose it, she would come over and let me sleep for a couple of hours. She had that perfect combination of helping but not doing.
