New here and looking for support

Hi. I'm hoping to find some support dealing with the emotions I'm feeling. The last year has been a roller coaster of my adult son moving back heavily addicted to alcohol and inhalants, putting my mom in a nursing home, my daughter in law dumping his kids on me to raise for 8 months, my daughter finally leaving her abusive boyfriend (but moving so far away I'm no longer able to see my granddaughter) and my life feels like it's unraveling. I'm self employed and my business is suffereing. My husband works away and is only home 1/3 of the year. The friend I used to talk to about all this has moved to the other side of the country and I feel kind of lost. I thought I had it all handled, but lately I just feel sad and I'm having some trouble keeping my life in some form of together.
