I simply do not have a green thumb for lavender plants.  I've tried various different varieties over the years but none of them would thrive for me.  I also have to be careful with things like lavender tea - for some reason it affects my hormonal responses.  Smelling it is one thing, ingesting it is quite another.  Thankfully there are many other indoor plants I can cozy up to!
