I NEED ADVICE HELP

I have just gotten home from a night camping with my best friend we just drove out their ourselve in separate cars bc we got out liscneses not that long ago and wanted to enjoy the freedom. My mum said it was fine for me to go so we left yesterday. I had an amazing time. Saying amazing doesn't justify it at all. I actually felt normal for THE FIRST TIME. I suffer from severe depression due to living with extreme anxiety since I was a child and a lot of junk with my parents separation. I am 17 and I do take medication for my stupid messed up brain. So anyway I was having an incredibly peaceful time with my friend. We swam at the beach and just were carefree. I felt normal. I felt happy. Not a lot of things make me feel happy, I've never felt like this before and it was only just this morning. Now I come home and my mum ruins everything. She starts telling me how WORRIED she was that i didnt' text her in the morning. I didn't text her bc my phone died. I explained this to her when I got home and i also bought a new charger that i could use in my car SO THAT I COULD TEXT HER. She knows ABOUT my depression but has no clue what it does to me and what I experience. I can't believe or describe the feelings I felt last night and this morning just being out of the city, camping, with my best friend, independently living our lives. She would never understand. So when she started going off about how worried she was I had to stop her I couldn't listen I said "MUM stop now, dont ruin my good mood, i am in such a good mood right, dont ruin it for me. I'm home now, my phone died, you dont need to worry anymore, life goes on, stop!!" BUT SHE KEPT GOING "she told me to "give her the keys" AND I LOST IT because I knew that meant she wont be letting me go anywhere again any time soon and that makes me honestly want to kill myself instead. The thought of not being able to go back to that camping place soon just because my mother is trying to "punish" me makes me want to punish her by killing myself bc thats what she's doing. She is slowly killing me and I can't take it any more. I ran to my room screaming and cursing, throwing things around. I was hysterical. I haven't been this bad in a long time. I think I have finally calmed down a little but when I looked at my camera and thought "i should look at the photos i have of this morning!" but then I bursted into tears again bc now those memories are linked to what I am feeling right now and I just want to be dead.
