Anxiety and sleep deprivation

I have a really hard time going to sleep and I have a newborn and I breast feed so all my breast-feeding mothers out there know what I mean. I can never sleep longer than an hour and a half to two ours tops ever. Even if my fiancé gives him a bottle I still have to pump otherwise my milk supply will go down.

But yesterday I was so sad and depressed I started crying for no reason about everything. Dramatic things I normally wouldn’t find upsetting. For instance I kissed my fiancé goodnight but I like to give him 2 or 3 kisses before I turn around and get comfortable to go to sleep and he pushed me away after I kissed him only once. I was really upset that my eyes watered and I started crying I couldn’t help it ! My hormones are so out of control everything is like the end of the world.

Does anyone know how to help this ? My anxiety is so extremely bad that every thing I do or say I doubt and question it overthinking every single action and word that I say and do. It’s draining and so stressful.
