You reclaim your life by first moving forward. What are your goals? What do you want to achieve? What about your art and getting back to your business?
I also think that sometimes we look around and think about the negative in our lives. Instead shift your thinking to counting your blessings. What is good in your life? Your kids?? Your art? Your therapist??
Feeling down is part of this process and with resolution of the underlying stress will come relief from the loneliness and depression. Are you exercising? Are you getting outside? I know you hate the fucking snow but bundle up and get your ass outside. You can do this love. You can.

Oh and the POINT is to come to love yourself more than anything and everything else. When I asked for my divorce, I was loving myself. I realized that if he would not treat his mental illness I could no longer stay. We were able to turn things around but that started with me realizing that I needed to do what was best for me because I matter. So do you but you need to believe that.
