Wow great for you! Boy I wish I could go shoe shopping with you lol.
When you go to B&BW, look for the lavendar like you mentioned. Other relaxing scents are rosemary and orange. There's a mix called Nemoli that supposed to be really nice too, I haven't tried it yet.
After your bath you can mix one or two drops of your oil or spray with a carrier oil like olive or almond oil and spread it all over. The heat, steam and body moisture mixed with the scents are so great!
I'm so glad to hear you're continuing. Maybe your emotions are heightened and that's a good thing?
