How can I become more positive about my divorce?

Give yourself time to grieve over the loss of your marriage and partner. Being on your own will give you a chance to get in touch with who you really are, and allow you to pursue new independent interests, even reinvent yourself. Redefine the characteristics that you're looking for in a relationship. Check online groups such as Meetup.com for events in your area, and pursue meeting new people. This is an emotionally turbulent time, but also exciting, allowing you the opportunity to make changes in your life as you open a new chapter.
