an emotional wreck

Hey ladies, how do some of you women get through it. My baby girl is 6 months old I love her with every inch of my heart she is my light and my joy. But I am just so miserable. As most women hubby works every single day does late night work I'm home all day with bubba from 7-7. I have let myself go and gained all my pregnancy weight back most days I hardly brush my hair put on make up and am so down in the dumps I don't want to leave the house. I am so lonely with no one to talk to and a lot of my friends have become distant since having a baby that I don't know who to talk to. My mum gets frustrated with me and tells me to stop feeling sorry for myself. I have a history with anxiety and depression (back 10 years ago) and I fear of falling into that old path. Please no hate comments just after some simple support, someone to talk to
