dd1s behaviour is so bad, she will push and push and push till i snap and shout, its getting to the point im not enjoying it and have literally felt ive lost control and am a crap mother and should walk away 
dd2 is 5 months and i know a new baby can affect dd1s behaviour but she is lovely to her sister and says how much she loves her and only the babys crying bothers her as it hurts her ears.
sheis good a gold at nursery and at anybodys house and basically very well behaved when out of the house.
in the house she screams, shouts, bosses everyone around, if we play she tells me what to do what to say who i have to pretend to be etc etc.
if someone goes to the toilet she has a tantrum screaming she wanted to go first despits not mentioning she needs the toilet.
if i ask her to get dressed she runs off/hides/says no/screams till im trying to force her into clothes.
she cant eat a meal without kicking her chair backwards, banging her fork, putting her feet on me, kneeling up, getting down from table, over and over.
she tells me she doesnt love me.
she says she only loves daddy.
she says i love you and the when i look at her she says she meant dadd.
she climbs out the bath while im trying to wash her.
she kicked me in the face when i asked her not to bunce on her bed.
she pushed her teddy in my face yesterday and when i said stop it she pushed it really hard in my face so i took teddy away and she screamed and tantrummed.
she will just look at me and when i look she will throw something or push a pile of magazines over.
she is attention seeking all the time, saying mommy mommy mommy and holding the back of my trousers so i cant walk.
i play with her all the time, as soon as dd2 sleeps i concentrate on dd1 and play with her, i read to her everyday and listen to her read, i bath her, i take her ad collect her from nursery and listen to her stories and what she has done, i praise her when she is good and always tell her i love her and how clever/loving/kind/pretty she is.
im at my wits end, getting out the house is hell and i have thought would she be better without me. 
please give me advice.
