is there something wrong with me?

im a 14 year old girl who has gone through a lot in life and my mental health has never been very stable. previously i have dealt with depression, anxiety and ADHD, but now something ele feels wrong. I've noticed how frantically my mood can change lately-for a few examples:
when i visit my girlfriends house, even the slightest thing she says that i disagree with can put me off her completely to the point i storm out her door, yet then i miss her deeply on the night and usually cry myself to sleep.
another example-last night i came home in an extremely happy mood for no reason, i found myself complimenting everyone i saw, replying to everyone on social media, i even spoke to my mom about lots of thing whereas usually we hate eachother. but this morning when i woke up my mom comes in saying 'wake up hun' as she does every morning which i am usually normal about, yet today i kicked off at her and when she wouldnt leave my room i started punching everything and cracked my walls. this had only happened a couple times before.
any help would be appreciated.
