Hi, I'd like to help you with your question.
The best place to start is to become sober. The alcohol is covering all of your other emotions and as you said, adding to your problems rather than helping. Self medicating by using alcohol and/or drugs is a common reaction when you feel overwhelmed and don't know where to turn. You can try working on becoming sober yourself but if that does not work, try a program such as AA, which as meetings just about any where at any time. You can also speak with your counselor about support through your therapy.
Once you stop using alcohol you may feel your pain is worse. That is natural and understandable. But there are ways you can address what is going on in your life that will help you start on the road to recovery and feeling better.
An empty nest, losing your horse, your daughter's divorce and menopause are all losses. Have you worked through your grief over these losses? There is a process you need to work through to come to acceptance and feel better about your situation. The stages of grief are:
Once you can work through these stages, you will have adjusted to the losses and you will feel better.
The best place to start is learning about grief and how you can work through it. Here are some resources:
You can also join support groups to help you feel less alone and to provide you with the support you need right now.
Your relationship with your husband is another issue. You mentioned that he is abusive. Dealing with an abusive spouse is a stress all it's own. It can erode your self esteem, cause you to feel depressed, and make you believe that you deserve to be treated abusively.
One of the first steps to consider is whether or not you should stay in the marriage. This is a decision that needs support and understanding from your therapist and from others like a support group, friends and family. Here are some resources on abusive relationships:
Reach out for help. There are numerous organizations and groups to help you either get out of the relationship (especially if you are being physically abused or are in danger) or find a way to separate and/or get both you and your husband help.
Do you feel your therapy is effective? If not, you may want to consider changing therapists. To find a new one, ask your doctor for a referral. Or you can talk to your pastor, if you attend church. Faith based counseling can provide answers that you cannot find elsewhere. Or you can search on line at http://therapists.psychologytoday.com/rms/.
Going through all that you have experienced can make you feel lost and worthless. But you are not. You are strong and resourceful to survive this far. Reaching out for help is a sign of strength, and that is what you are doing here. Surround yourself with people who can help and offer the support you need to climb out of your situation and get back to doing what you want to do.
I hope this has helped you,
