Kudos for seeking out help.

If you've only been on Lexapro 10 days and already noticing an improvement you're in for much better things. Lexapro, in my experience and others, hits peak effectiveness at about 4 to 6 weeks.
Glad you've noticed the increased ability to focus on life. That's the #1 thankful improvement I noticed in me. Gave me the ability to deal with my anxiety.
Are you also getting therapy? Would highly recommend it. Your primary care physician can probaby recommend a few. Medication alone won't free you, but that's just my experience.
