I feel so stupid

I feel so stupid. Yesterday I got a phone call from someone claiming to be from the IRS. Now that I think about it, it was obviously a scam because the IRS doesn't call people. Anyway, I gave them my banking information and my social security number. I feel so stupid. So today I've been doing damage control. I had my bank account changed and I had a lock put on my credit. I'm just so upset with myself.
