What can u do to increase my speed and stamina 🙏

I’m starting to not enjoy playing basketball, I haven’t played any matches since summer and practicing by myself everyday is getting boring and honestly making me hate the sport, idk wether I should quit, take a break or keep playing

Had a Game today got faced guarded lost by like 50 points. My attitude was off I kept getting mad and just stop trying mid play. I had like 10 points and wasn’t the leader I was supposed to be. I delete instagram and TikTok to focus on my mindset and skill.

I am a basketball player who made varsity. I don’t get many minutes and struggle with confidence. Today I got my chance and played and traveled the ball twice passing up wide open shots and I am extremely frustrated. I play for hours everyday and those shots I passed up is something I would shoot no hesitation. It’s really frustrating because I want to play more but I messed up my opportunity. Does anyone have advice on staying calm in a big game and work translating?

i got cut from my hs bball team, i am sick right now, depression and anxiety are hitting hard. please help me
