Epiphany?

I've spent the last week home alone. Both my mother and grandmother had went to the coast, I however, couldn't find anyone to go with.
In the past week I have felt great, filled with energy, with joy, having fun. Not once did I get angry at something, not once anxious.
However, now that they are back, my old self is back as well. Angry, sad, without the will to do anything. Just exhausted, like they drain me. I get nervous at every word they say to me, can't sit still, and I've spent yesterday night and today afternoon crying (or trying not to, anyway).

Is there hope for me, that I'll be normal when I move out to live alone? That I won't freak out at everything, and that I won't have to comfort myself every night or try to not burst crying in front of everyone?

I certainly hope so.
