Some people just make shit not very good parents.
Your mum may have done the best that she could, the best she was capable of, but that may mean that some of her issues have been 'passed on' to you.
Btw I was depressed as a teenager too - and to have clinical depression as a teen or a child shows that most likely there are psychological issues from childhood that need to be tackled.
You say she defends herself by saying that 'obviously she is fine as she has lots of friends' (therefore there must be something wrong with you) and this reminded me of my mum, who is a very, cold, loveless person, and she always says that it obviously isn't true as she is in a caring profession, as a nurse (so obviously there is something wrong with me).
It strikes me that both things are odd to point to! If someone said to me, you are cold and emotionless,I wouldn't say oh but I have lots of friends, so that can't be true, I would say no I have a great relationship with my daughter, I love her lots, I empathise with people, I like to help others etc.
She knows you're right and she won't / can't admit it and so shifts the issue - I have lots of friends, you don't, therefore the problem is you, not me.
Up to the age of ten, I could have written you post, unfortunately after that things got worse and did go over into the area of emotional abuse.
It really messes with your head. A mother is supposed to love you for always (I also got told I love you but I don't like you!) but sadly not everyone is actually capable of loving their children as they should be loved.
I hope this sets you off on the right direction and that you find peace.
