help on accidentally using the wrong tone and upsetting people?

so like with the whole lockdown going on ive been a lot more stressed

this has led to me doing this thing a lot more where i accidentally use the wrong tone when speaking and come across as angry or annoyed and this upsets the other person bc they havent done anything and then im upset and its this big cycle

what makes it worse is when i feel myself getting worn out i try and purposefully sound more chipper but apparently i just sound even more sarcastic/annoyed!

if anyone else goes through similar things and has some advice id much appreciate it!
