It's has been getting worse and worse, feels like I'm back at square one. Feels like the Ativan hasn't been helping as much lately. Idk what to do
I suggest you tell your doctor what is happening and ask for an Ativan dose increase. I know this isn't easy when you're suffering, but bailing at this point is likely to only prolong the agony if you have to start from scratch on another antidepressant.
You could try taking omega-3/fish oil capsules. They have anti anxiety properties, but there is also some anecdotal evidence that they may speed up antidepressant kick-in a little though this hasn't been supported in a couple of small scale studies. Start on 1 capsule a day and increase it by 1 every 3-4 days up to 4-6 capsules/day.
And try to be busy to take your mind of all this. Go for walks, read an engrossing book, play video games, anything.
