In times of slow Internet, Thunderbird repeatedly says sending timed out, but it actually sends, resulting in multiple emails.

That about sums it up. I feel very unprofessional when it happens. Can I determine from within Thunderbird when it sends or doesn't send? How can I fix it? Is there a way to tell Thunderbird to prevent multiple identical emails?

When it times out, it won't appear in the Sent folder. Right now, to see if these timed-out emails actually sent, I have to open my web interface to gmail, which is the only place it'll show a complete roster of sent email. (I don't like the web interface, which is why I have Thunderbird in the first place.)

Thank you. After referring to these articles and checking the gmail settings, the SMTP appears to be correct. Also, this only happens when I have very slow speeds, and at all other times, Thunderbird does exactly what I expect it to do with outgoing email.
