im tired i dont wanna be strong anymore or show people how independent i am i just wanna rest

I just did a very hard school presentation yesterday, and I failed. I was supposed to do this, I did my best but ik that wasn't enough, I know I didn't even try anyway, I even procrastinated and had urges to put it off. When I was at the front, mind went blank and I tried to talk but then my voice was shaky, the second I knew it my hands were too. I even mustered up to speak in my own words.. but I could barely think and make out what I was saying without stuttering. I was alone at the front, being an absolute embarrassment and getting crushed by my own nervousness. In the end my groupmates said "it's okay, you did your best, thanks for saving me, I wanted to help u too but I was scared". Ik they're lying, you'd only do that bc thats the 'right thing to do', I know you ppl were thinking and talking behind my back like"wow you could've done better". But tbh, you guys didn't fucking do anything. I was the one who made the ppt, wrote the paper, bought shit and printed it. I FKIN SUFFERED

I just LOVE when people argue, ignore me or shut down when I try to explain why things work or why something is happening for them, For context, my IRL was talking about how she'll get dizzy when she went to stand, I having mentioned that she needs more iron and salts in her diet to prevent that, she unfortunately argued and said she didn't and that she didn't understand why her doctor sent her to a nutritionist (she has suspected ARFID, as I was told before), and I yet again explained that her doctor took into account the symptoms she told me, and wants her to go to a nutritionist so they can figure out what she needs in her diet; My IRL got pissed and said that she didn't like that and she doesn't need help because it's "weird and unnecessary", I was starting to give up, so I said that her doctors were looking out for her and that it's normal not to like something but it still needs to happen (example: boosters), and all you can do is power through it. She then ignored me. wtf.
