Help

After 52 years my mother has finally destroyed me.  My whole life she has been a narcisist and control freak.  As a teenager, I had to deal with her being a closet alcoholic.  I always new from how I was treated that i would be diagnosed with something.  So, 15 years ago I developed panic attacks.  Took Paxil up until now.  Paxil was making me fat so I decided to go off and take Wellbutrin.  Don't think it is working to well.  My anxiety is still up there, but my mom now 88 and has mild dementia is torturing me.  I cannot cope anymore.  I took her in to live with us and its been a nightmare.  I am stuck. The person who has ruined me my whole life is still doing it and now to my kids.  I am going to try and put her in assisted living, dont know if I will have any luck.  I am feeling like I can no longer keep it together.  There is only so much diazepam, wellbutrun and buspar I can take.
