I can't seem to stop being angry at everything

I don't know what's wrong with me but lately I've been snapping at everything and everyone , I'm tired and groggy all the time and the only thing I can think of is the Lexapro I'm on but it's such a small dose and I really don't want it to be that because I've been through 3 different med trials and they've all failed and I just want to melt into a puddle on the floor.

We're potty training at the moment and my 3 year old seems to think using the potty doesn't apply to him so that's been a circle of hell I didn't know about.

I was already depressed before but now more because we have to move away from my village and I feel like I'm being hounded for when we're having another (my answer is a big fat no, I don't think I ever want to go through ages 2-3 again)

I just feel super awful and I'm so tired of everything, thank y'all for letting me scream into the void for a second cuz I feel so low it has put me into a pretty tough spot
