Don't threaten unless you are going to go through with it... You need to start thinking of yourself if you are getting depressed this is not a good thing for YOU and if YOU are not healthy in mind/body/soul then your immediate (DF and DS) are going to start to suffer for it. I know it sucks but you need to get tough and stand up for yourself chicky. You are not their mother you do not owe them anything or HAVE to be here, they are taking you for a ride... xoxox Big hugs.
