Does anyone else struggle with anxiety?

I feel like ever since I had my first child 3 years ago I always feel overwhelmed or as if it's hard to breathe going anywhere or doing anything. I get nervous and always think of the worse possible outcome to any situation.

Now being pregnant with my second, I'm even more overwhelmed. The thought of taking her to daycare anytime soon makes me upset and filled with worry.

I took Zoloft after my first pregnancy to help with anxiety and depression but I didn't like how I felt on it.

Any recommendations on how to cope with anxiety? Or just to be able to breathe a little without always feeling completely overwhelmed?
