Toddlers are tough. Then all of a sudden (almost) they snap out of it and become delightful preschoolers.
Find an activity to do outside EVERYday. Go for walks. Stop and look at flowers. Take a class just for yourself. Take a different class for your toddler and you to play together.
Check out local craft stores. Likely there are holiday things to do. (You can participate even if you don't relate the religious side of the holidays.) This way you will start creating holiday memories for your child(ren).
Do something fun - EVERY day.
It will get better.
There are many posters here who have been where you are now. They have created good supportive friendships for themselves and their children. Besty and SweetPea come to mind. Maybe SweetPea can tell you what helped her to make new, non-conditional friends...
