Am I just not meant to be a SAHM?

I quit my job a few months ago to stay at home with my daughter. She is now 14 months and I am so bored and lonely. There is plenty to do with my daughter and around the house, but it’s an isolating loneliness that you just don’t understand until you do it. I see my family and friends making new friends through coworkers and get jealous and feel even lonelier. Will this get better as my daughter gets older and we can go more places to play and get out? Or is being a stay at home mom just not for me? Does anyone have any advice?
