Sad and depressed

Today I been sad all day. I’ve been doing everything for self-care trying to get sleep working out at the gym eating healthy. I even went to church today as I usually do on Sundays. To try to find some fulfillment because I’ve been feeling like I’m on the verge to cry. There’s no particular reason besides just not feeling good enough or failing like I’m losing my self. I am a single mother of three kids son 17 daughter 12 and my youngest 3 1/2. I do it all by myself and sometimes I do get overwhelmed and I’ve been single for over two years and I’ve tried to date but it just doesn’t work out and I don’t wanna depend on a man for my happiness. But lately I have been feeling really lonely and sad. If anyone can relate, let’s chat let’s be friends.
