It's a damned shame that so many docs will just throw about all the SSRIs at a patient without thought about different types of ADs and even possible combinations. Really, a doc should try 2... maybe 3 SSRIs and then move onto a different class of AD or add something to augment or another AD in combination to the SSRI if there's at least partial success with the SSRI.
Has your doc discussed different classes of AD's or any combination strategies? If not, fire your doc so to speak and find one that knows what they're doing. You want a psychiatrist, not a GP. If you have to make sacrifices to cough up the money for a good psychiatrist, it'll be well worth it.
In my experience, the various noots, adaptogens, and other various supplements are great for augmenting my AD and ADHD medication but the prescribed meds are truly the meat and potatoes of the treatment.
After only a few months, I got the same uncomfortable emotional numbing effects, the amotivation, and weight gain from lexapro. Pamelor (generic nortriptyline) was a much better AD for me. It doesn't cause any of the numbing, it lifts my mood, and it helps with my anxiety a lot. It is a tricyclic AD and that will scare off a lot of younger docs but it's one of the newest TCAs and just as safe and tolerable as some of the older SSRIs like paxil and luvox and arguably more likely to be effective than any of the SSRIs. Not everyone responds well to the SSRI MOA and need an AD with a different one. Even if you don't like the sound of Pamelor, there are other ADs in many classes other than the SSRI category to discuss with your doc.
If indeed all your doc did was chain prescribe one SSRI after another without thought or discussion in regard to other types of ADs then I am truly very sorry about the lost time and pain you've endured largely due to the doc's incompetence. If this doc is a GP, understand that this is commonly all they know to do and just aren't familiar enough with mental health and associated medications to go much further than to keep trialing different SSRIs. There's a good case for the prescription of ADs be limited to psychiatrists but that's a thread of its own. If this was a psychiatrist, I'd personally be fuming and very well might give'm a piece of my mind.
