I struggle watching my 90yo mother age. How do I cope with this? I’ve been raising my 8yo grandson for 4yrs. My son died and my daughter-in-law drinks; should I try for full custody? How do I deal with vacillating and self-sabotaging behaviors? I lose my motivation to follow through. My daughter received a text about her fiancé and it strained their relationship. What can I say to her?
