First, OP, I sympathize with your sense of isolation and I know some PPs will have other suggestions for you.
I just want to say that the above sentence reveals an unrealistic view of reality--that is, the reality of most moms of school-aged kids, whether single or married. I think gratitude is one of the biggest keys to happiness, and one secret to gratitude is what you compare yourself against. If you compare to some unrealistic dream--the above quote--you are setting yourself up to failure when it comes to gratitude, and thus, happiness. If you compare to what lesser situation you had before, or to other people's plights (i.e. there are so many people with bigger issues, worse issues, health issues, etc) then you will feel gratitude for your situation.
This is *not to say* to not try and improve your situation by coming up with strategies to do so. This is just one of the strategies--a mental strategy.
I think this is excellent advice, especially around cultivating gratitude. I have to agree that Broadway shows and flirting in bars aren't all that common for most mothers!
I would focus on building health and wellness and fitness for myself and my DD, and on building a village around my family. Other posters have great suggestions for that. It is like dating, in a sense. Really, there are many other women like you and you can build a community around yourself and your daughter. Good luck!
