In my opinion hun, you need to find a friend to live with or somewhere by yourself. Not only is it stressing him out, its stressing you out. Your fish will also get stressed. lol
I can't go 4 days without wanting to do a water change because my fish are messssy eaters. A whole month? I don't think I could do it.
You need to think about you, what you need in order to be happy.
You're my age, I honestly love living on my own, yes the bills suck but it beats
someone breathing down your neck all the time. My mother was angry at me
for months when I moved out, but I knew this is what I needed in order to be happy.
