Regret sending an e-mail

I regret sending an e mail to my daughter threatening to even hit her if necessary, if she continues treating me badly.

Since an adolecent she has been agressive, disrespectful and unconsiderate with me. I have always told her,that I don´t like her manners, but she doesn´t find any wrongdoing in her behaviour.Seems that noone ever takes resposibility for their acctions.

I sank into a mayor Depression because of that and some other issues.

I have swallowed my agression not to make things worst but I took it out in that way.

I assume she is mad with me and might not talk to me anymore, but I have swallowed my hurt feeling for too long.

I regret this things happend between a mom and daughter.
I´m not sure if I did a mayor mistake or probably a good thing. Not sure...

This is regretable
