Give yourself time. Slowly, as you get to do other activities and maybe meet new people, yo will fell better and better.
I heard it's normal to go through a process to let go on all the years you spent beside someone. You had a life with that person and created a whole world around it. Now, it's time to rebuild and it's not easy.
Only time will help. You are already moving in that direction, you just don't see it the way we can see because you want it all clear now. It will get better.
And, just my opinion, don't be so worry about other people's opinion. They don't know your life, your reasons and it's nobody's business but yours. Don't be so self conscious.
You will be fine, just give yourself time and be gentle with yourself. Who knows what the future holds...
