Speech disorder

[Jeordie]

Does it happen to you? Often I switch words, especially pronouns, and think/say things like "I think she liked her" instead of "I think she liked you", things like that. Or "I'm going to the milk to buy the shop". Yes, laughable.
Sometimes, it happens mostly when I'm trying to fall asleep, I forget what I was thinking. A strong fear arises after I do, as I'm afraid I'd go totally blank.

Can this happen just because of anxiety and stress, or do I have a brain damage or something....

I can have a stammer sometimes. It comes an goes in intensity largely based around time of year (worse in winter) and educational pressures.
