What do you think about me being depressed for basically the entire year?
What do you think was the cause of your depression?
My mother has been cheating on my father for several years.
If you feel you are depressed then it would be very helpful to find someone to talk to about it. In addition to that, possibly seeking professional help would be something that was very beneficial. Lastly, you could always try eating a healthier diet to spearhead your mental health change.
I don't want to listen to some shit you are suggesting. If you keep it up, you will be calling my mother a slut and I will set the internet against you.
No, I don't think that anyone in your family is a slut, but you do need some help. You're clearly not right at the moment and a therapist or someone who cares could be there for you right now so that you don't need to suffer.
