Depression/anxiety

Hey everyone.

About 3 years ago I was diagnosed with depression and anxiety and got put on lexapro. But it made me gain a fair bit of weight, I only stayed on them for a year and have been off medication since. While speaking to my psychologist while i was medicated she recommended I changed to an SNRI, but I decided it was time to stop meds. But now it's hit harder and im really struggling.

So I guess my question is if anyone has experience with this. What is a good SNRI that is less likely to make me gain weight but also effective, my poor kids deserve a better mum that isn't constantly down and out and lashing out :(
It's a mix between PND and just horrible life problems with anxiety chucked in the mix.
