I swear I'm so depressed idk what to do with myself my SO left for god knows how long he moved in with his dad so he could get a job cause I live with my dad and their is no places out here for him to work its in the middle of nowhere... so he moved their so he can get a job and save up to get a car then move back down here with me cause we currently don't have a vehicle... I'm seriously so broken down I can't eat I can't sleep I'm sooo exhausted from crying ao much idk what to do I swear. I have a 4 year old little girl here with me at my dad and my dad and step mom are always gone so its just me and my little girl here. so all I can do is think about him 24/7 sorry didn't mean to write a novel I just need someone to talk to I'm so broken its unreal... idk how much longer I can be without him and its only been 2 days... someone please talk me through this...
