36 weeks and can’t take it anymore😥

This week I’ve become extremely miserable and angry. I already suffer from depression as it is and I’ve been getting really upset easily especially with my 2 year old who just doesn’t listen to me at all. I feel horrible after I get upset with him. I just burst into tears and want to say screw it all. Not sure why I’m feeling this way all of a sudden since I’m still on my meds for the depression. I just don’t know how to handle these last few weeks. I know most of my anger/instability is due to me being in so much pain and unable to walk or stand for more than 5 mins. I just hope things get better soon or once baby comes cuz I’m starting to give up hope😥
