Normal to have depressive episode 2 weeks in?

A little bit about me - I am 39(f) and it has been 2 weeks of 2.5 mg Lexapro. I've had anxiety and depression for majority of my life and am posting to see if anyone else has had a similar experience?

I've been in dark spaces before but have always managed to mask myself and carry on as a "good" employee, mother, wife, daughter, and friend. I started Lexapro after fantasizing and attempting suicide in the garage (not my first time), and decided that Lexapro would be one of my final attempts to fix my mind.

I'm really good at masking myself, but today my spouse really triggered me with his condescending comments, and for the first time today, I can't hide my emotions. I am so depressed today; I can't work and am just laying in the couch like a useless meat sack. I typically cook and clean after work, but I can't even function.

Is Lexapro debilitating for anyone else? I have seen positives almost immediately, but I am finding that Lexapro has enhanced my depression today. Is this an isolated experience? Appreciate any thoughts.

Edit: spelling "debilitating"
