Escitalopram for depression

I hate my life, or actually I hate how my life is now. I loved life before, I was happy, I looked after myself, I felt excitement almost every day. Now I can’t remember the last time I felt excited about something, I’m always stressed, I’m overwhelmed, I always find myself screaming “I hate my life!” And I don’t know where I went wrong. Back when I was a single mom to my son I was happy, I had everything figured out. Everyone had said single parenting is hard but I loved it. Now I’ve been with my fiancé for 8 years and we have since had a daughter together who is now 3 years old.

Since then I have gained 50 lbs so now I am overweight, my house has gotten out of control, I’m stuck with every responsibility on top of working full time. My fiancé just got a puppy against my will but he works every evening and now is busy every Saturday. He works at a gym and makes that his life. So I’m stuck with so much responsibility that I have no time to look after myself. My hair rarely gets done, I’m lucky if i get the chance to shower every day, my house is a mess, my self esteem has taken a beating. I do t have moments when I get excited for something or when I feel pretty. Those feelings no longer come for me. I always just feel anxious, overwhelmed, or unhappy. So cut to the chase, my question is first of all does anyone here have experience with other escotalopram. And then would being overwhelmed count as depression. Like I know that if my fiancé did more to help and was home more so I could have a bit of time to myself in the evenings and weekends then I’d be happy. But I know that’s not an option so would taking this pill be worth it or is this just hopeless?
