Now my TBird email has a spining circle top left and isn't getting any new mail. I restarted computer but no help. That email I tried sending from TBird isn't in Sent, or in DRafts or TRash.

how do I get rid of the spinning wheeL??

Have you tried with a smaller message? If it works, then see below. If not, check your sending server settings.

While there is a technical limit [= several email servers refuse to send/pass on bigger messages] of c. 10 MB, you will hit performance issues earlier. It is also quite possible that some server [like your sending one] interprets your attachments as harmful, so thereby blocks the message. Also remember that people have more and more become allergic ,so to speak, to attachments, so a better way is to store attachments to cloud storage and provide only a link to them in your message. There are even plug-ins to Thunderbird which automate storing and linking.
