Lexapro or Zoloft ?

33 yo female

I worked really hard the last 2 years to get to a healthy weight. I do not want to gain weight but I have very bad generalized anxiety with some OCD like tendencies such as ruminating thoughts ect

I have children so I can’t have something that sedates me for long term.

I have some minor IBS so also don’t want anything that would flair that up long term.

what worked best for you / woudl work best with the concerns above ?
