I feel so alone

I have no help from my bf to take care of our son... he likes me to himself and I feel so isolated from everyone  
I wanna go somewhere like a friends or my moms and he complains about it .. he doesn't help mr with our child.. all we do is fight 
I'm mentally and physically drained :( no happiness or motivation to do anything and no I don't need any pills... I'm already on Zoloft
