Is my friend a emotional vampire?

I have known this friend since kindergarten.
Our parents have been friends since we meet as kids at kindergarten.
As a child I recalled she wasn't fully kind to me. I had to hang with her cause our parents were friends.
She use to call me Zandy Dummy. Zandy is my nickname.
We use to fight a lot.

Her parents broke up when she was like 2 or 3. Then her father died when she was 7.

After that at that time she once told me that my parents would break up. I said they never will. Well in that year they did.
I do wondered if she over heard some thing from her mum talking to my mum. But it was hurtful.

As we got older we grew apart and she always had one best friend for couple ofbuears and it will fall out. This happened even in high school.
At high school she use to party a lot, drink a lot, and had sex at very young age. Probably 14 maybe.
I was never invited to these parties or hang with her at school.
When I was buillrd at high school their was no support from her at all. I literally had to change schools cause these other girls kept bullying me even though teachers spoken to them etc.

When we hit in our 20's and she moved to study she kinda went down hill from there. She was flatting with her boyfriend but eventually they broke up. She told me she broke to with him because she notice if she gets bored talking to them she just cuts it off.
Also, my friend is abit stubborn\ wild. I guess she wanted to do things that her boyfriend at the time said no too.
She eventually left university cause my mum show my sister this paper study how you don't have to study in order to get a job. So she take that as fact and left. She drinked a lot, and would have sex with randmon men. She even had sex with her friend we name him Matt. Who say he was gay but she was trying to show him he is not gay by having sex with him. They would for this even with Matt's boyfriend around when he was asleep. She would smoke weed, take mushrooms.

My younger sister would hang with her. But it was more my sister was looking out for her. Like she alright. Oh night, my friend left my sister in the city and she went to have sex with some randmon man.
She still owes my sister after all these years $300. Which she probably forgotten.
She wasn't kind to my sister she would have digs at my sister saying how her hands are too big, or when she was studying was better than what my sister was studying. Other stuff.

Eventually she got with this man who was bipolar and he use to before meeting her drink blood from his pervious ex girlfriend. Cause he believed he was vampire. There was episode a couple years ago she called thebpocile cause he threat to kill himself. Tere was 4 pocile men that had to hold him down. He went to therapy a very short amount of time but stopped.

Now, she just had twins last year and live hone with her mum and her partner. The mother gave up her big room for her daughter and twins and the mother has a small room downstairs.
I believe her mother pays for most things. She looks exhausted.

Now here is my question.
When I visited her when she gave birth to her twins at hospital. I saw them and they opened their eyes. I said "aw....they are actually cute". Then my friend said "oh actually cute", I said to her "I'm sorry I didn't meant that way" she said "I know I was trying to make you feel bad". Which she said that I was shocked and my cheeks burnt up. It bothered me so much that evening I had a tummy ache.

I told my therapist she recommended to cut off with her.
The problem is my mum is friends with her mum and I knew her like ages. So I feel guitly.

I thought to giver her a chsnce so I see she asks me to come over and see her and twins once a week. Usually its at the park.

But it hit me when I visited her short time for Christmas. I went with my partner we said hi and then she gave me and my partner the twins and said we can be "baby sitters" and sat down cross her legs and smiled.
I felt responsible prevent the one twin going towards the BBQ.

Then I just visited her this week. She seemed terid because she had some boob infection. She asked me to come because her him on hpilday and her partner at work.
I brought her a birthday present cause it was her birthday in couple of days. But when it was my birthday last year she didn't got me anything or my sister even her mum didn't. They usally do since I have known them. I thought maybe it was because I didn't went to her birtday last year out of fear she might say some thing mean I be upset. So my mum went but I still brought her present to give.
But I thought doing oppositr of that might help bridge the gape. Though she didn't went to my birthday couple years ago my sister did this game board/characters to do and she was suppose to come but didn't. So my sister went over and found out she was high. My sister was massively angry and disappointed.

Anyway, when In was there it felt like In was their to help her look after the twins not friends. She said her aunt coming over she hasnt seen a while. That its good to have extra help.

Every time I see her and the twins afterwards. I feel drained, exhausted, I need to relax and recharged myself. Every time.

I just wonder if she is emotional vampire.
I am a empath which my therapist told me I am. I have heard empathy can be taken advantage.
