Is this a toxic friend? ?

Here's my friend's personality (M not faking it just to get everyone to say She's toxic). It's based on what I know.
Although she's a fun and helpful person, but s.times its hard hold back her attitude.
1. COMPETETIVE : she competes with me in anything. Ex: if I have done s.thing better than her, She feels uneasy. And my goal and hers is to become an architecture, she brings up irrelevant information and skills ( s.th everyone knows) just to show off that she's better than me. Also I've been doing artwork since I was in secondary school, she's just started it, she constantly asks how many pieces of artwork I've done today cause she has done alot of it.

2. SHE MAKES FUN OF ME CONSTANTLY : When I finally reach my limit, who's the
victim? She is..

3. TALK SHIT ABOUT OTHERS : she often has negetive things to say about people. Although s.time it has n.th to do with her.

4. SELF-ABSORBED : she keeps talkin about herself like how bad her day and her life is, how sad when her printer was broken, how much doubt herself in study although she scored 64/75 for writing ( She clearly knows m no better than her, but she still needs attention from a girl with a worse situation). She says stuff like no one's better than her, she's unique.. she often interrupts people' talk so that she can follow the topic and add her own story like there's only her on the planet. But never give a damn effort to listen to anyone's hard problem, she will lost in thought abit and add her own problem in again..then the blah blah blah about herself keeps goin none stop..

Please, Let me know what you guys think about it. It doesnt explain much, but as I am her friend, I m close to her, and its hard to handle her attitude.
