My gf is acting crazy. she can't sleep at night and shes very snappy. we have been fighting a lot recentley. Shes in grad school and is stressed out, we also just got a dog (we live together) and shes stressed out about that, she might be stressed about me but I really dont do anything except put her in line when she does stupid sh*t. But she just gets really moody and on the edge ready to snap. I just get kind of hard show her tough love sometimes cause she needs to grow up. But what should I do right now ive never seen her like this? should I just let her be by herself and her friends or try to help her? She always says she wants to be left alone when shes in a bad mood.
