My 15 year old daughter is SO disrespectful!

After her I swear not to have anymore children. I can't imagine ever doing this again.An altercation between my daughter, boyfriend and I occured.My daughter is 15. She was playing a computer game and kept screaming loudly. I asked her to stop because we have neighbors and it was getting late. She kept screaming I took the computer. There was a power struggle. She had choice words for me.My boyfriend stepped in and helped me to remove all electronics. She pushed and shoved him to get them back. Swore at him, flipped him off and cursed at him. She pushed me as well and I almost fell over. Her strength is incredible. Poor guy I think he's on his way out of this relationship and I dont blame him. If I was him I wouldn't stay.I feel shame and embarrassment.She just recently gained some electronics back after three weeks without them and then goes and does this. Now she has nothing again. She was just recently discharged from a clinic for mental health reasons and she had one altercation there with staff as well. They didn't diagnosis her with anything other than the same old depression and feel that she's stable.It's draining because there's so many different sides to her. She's lovely, funny, childlike and then also defiant, mouthy and rude with NO respect at times. She's called me the b word, put her hands on me amongst other things.When her outbursts are over she appears to reflect and then goes back like nothing ever happened!She's on meds but I wonder is this all because of my parenting? Was I and am I really that bad of a parent or is there something else going on? I'm worried about her future. I feel so much shame,anger, frustration. Sometimes I think removing her from my home and having her live elsewhere would give her the best chance of having a successful life.I've tried and I'm trying to help her. I won't give up on her.Just looking at her, at her age she has no friends and is extremely close to me, doesn't understand boundaries, acts very young for her age at times and has these odd tendencies. She might never ever have that teenhood that I see so many other teens having. It's so sad.I needed to vent but would like to hear other parents thoughts. via /r/Parenting https://ift.tt/2J8Y7hv
