My brother and I have been sleeping together for a month. Are we too late to find help?

I (17F) haven't slept in my bed for almost a month. Every night, I go down the hallway to the living room and I sleep in my brother Aaron's (19M) bed. I've never been the best at sleeping alone. I can't explain the reason why. I've been to therapy. I've learned ways to do things, but I've come to realize I don't like that and I can't do that. The one thing that was always there for me and always made me safe is the sleep option. <br><br>It's not like we have sex or something. We just look each other in the eyes, go to bed and fall asleep. I don't even get to see his ass in pajamas or his morning wood (well, I've seen him in undies but he wasn't erect, so I didn't count it). <br><br>My question is: are we too late to find help? I've talked to Aaron and he also agrees that it's not right but he's also being selfish enough to not want to do anything about it. I don't like being selfish like him. I'm being selfish sleeping next to him when I know it's wrong and I don't want to. So I know that I need to find help. But are we too late for that?
