I agree.
And remember, J, that if things ever get really bad, and suicidal or violent thoughts are dragging you down, there are helplines that you can call.
I found some for you, before, in California.
Do you have those numbers to hand?
Phone them for support, if you need extra help.
You could phone them, anyway, just to get things off your chest.
We all care ~ remember that!
I think that, perhaps, the situation at home gets harder to deal with if & when you feel unsure about the relationship with your girlfriend ~ and vice versa. Is that correct?
When you are just a little bit older, I think that you will have more freedom, to spend more time with her, and less time at home.
