Joann - Think "baby steps" - there will gradually be days when you feel a little better/maybe can do a bit more, followed by days when you feel worse again (maybe from overdoing when you felt good?)
Some things that help me get through the tough times are pictures of my loved ones, phone calls, good books and hot coffee or warm tea. I make a conscious effort to maintain positive thoughts - I do "three things I am grateful for today" or "three things that bring me happiness." Some people on Connect maintain a gratefulness journal to look at when they feel down. When my husband's arthritis flares, he swears by a good soak in the tub.
