Hi @Sosad76,
Welcome to the SANE Forums!
I am Shimmer, one of the moderators here 
It sounds like you have been through a lot, with your depression, anxiety, numerous deaths and your ex-husband's affairs. I'm really sorry to hear about these things, particularly the loss of your babies. At the moment this all seems to be impacting your mood, alcohol use, relationship and work. That's understandable, I can imagine it being very difficult to cope with everything.
You mentioned that you had thoughts about ending your life. If you are thinking about suicide and feeling unsafe, please call/chat online to a crisis helpline:
Suicide Call Back Service: 1300 659 467
Lifeline: 13 11 14
GriefLine: 1300 845 745
Good on you for reaching out on the Forums for help and to explore with others how to cope better. I'm curious, what are some things that you already do that you feel are helpful in coping? It's great to hear about your great career, beautiful daughter and new husband - I'd love to hear more about their positive influences in your life.
You mentioned that your life revolves around caring for others - I'm curious, do you take any time out to look after yourself? Self-care is so important to our mental health 
Once again, welcome @Sosad76, the Forums are full of wonderful supportive members like @Kurra, @utopia and @Heart, I hope you find being involved helpful in your journey towards feeling better.
Take care,
Shimmer
