Depression coming back

I’m 24 years old and pregnant with my 2nd. With my first pregnancy I had depression and was diagnosed with post partum depression after my daughters birth. It’s probably the lowest point of my life.

Well, I’ve been feeling like I’m falling back to that again. I find no joy in things. All I want to do is lay around. I’m angry and snapping at my loved ones for no reason. It takes all my energy to get out of bed. Chores and things are getting neglected because I have no energy to care. I get overwhelmed really easily. My daughters in a terrible stage right now and I’m constantly stressed. It feels like I’m putting on a show in front of people.

I’m so scared to get back to that point I was before. It feels like I’m getting there and there’s nothing I can do to stop it. Besides therapy, what are some things I can do on my own to get out of this? I hate feeling this way. And I don’t want it to get worse.
