Used to

In the school during our English lesson, we were learning about expressing habits - used to; and also the difference between used to and be used to. It inspired me a bit. It may or may not be useful for Meldath or someone else, yet at least it could be interesting.
But forgive me my egocentrism.

I used to play chess.
I used to go to judo courses.
I used to brush my teeth for one hour.
I used to go to a confectionery every week with my mother...so I was used to that everyone laughed at me that I was fat.
I used to play computer games for two hours every day.
I used to shout at people that didn't want to do what I wanted them to.
I tried to get used to my mother's illness...with no success.
I've got used to my siblings...and now I pity I didn't use to talk and play more with them - hopefully it's not too late yet.
I got used to my classmates...though they still surprise me every now and then.
I used to talk little to other people.
