I guess I can only really say hang in there. I was divorced before 25 and embarrassed about it, and there were times when I really struggled with wondering whether I had done the right thing to break something that was mediocre but not horrible to find a happier future for both of us. Within about 18 months, I had met someone new that pushed me and inspired me, and we travelled the world for a full year, through 20+ countries and varying experiences. About 8-9 years later, we're married, have built a new house and I can barely even remember that time during and after the divorce. Stay busy and social. Time alone mulling it over is often difficult.
