Wow that's ALOT of bags and the bags you bought aren't the lower end of the price range either (le tal, miroir speedy, mono riveting).
I may be the minority here but it's a bit frivolous to buy all these bags in 1 month. UNLESS you do have the finances to do so and not get yourself in ridiculous debt. If you're feeling guilty already (and you stated that you NEVER feel guilty), then it may be a sign not to be hasty with the shopping. Gorgeous bags will come this coming seasons. You will have more wants, IMO the feeling of purchasing a bag at a time is much more sweeter than to be swimming in bags.
Then again, I'm a different person, I like to cherish and make the most of every bag I buy. I choose my pieces after ALOT of thought and deliberation. My next stop is a Hermes, so I have to DELIBERATE for a long while before I execute on my purchase. Just don't let the guilt overwhelm you, if it does, then it's a reality check and revise your purchases.
