Getting hell lot of stress at work

I am a fresher and have just joined a tech company with a decent pay. It’s been only a month and I already want to quit. It’s not about the people here(they are good), it’s about me only, I am not able to meet deadlines. I admit I am a loser and not made for this. I still like doing dsa and solving problems but ofc corporate demands none of it. The tech stack here is new for me, the whole architecture is too complex to understand, I don’t know how to proceed further. Even now I have many tasks aligned up and here I am writing this stupid post which I never would have imagined I would post. I don’t know why I am even writing this post coz everyone will just say these general things like don’t take too much stress, manage your time well, ask for help from colleagues/senior when stuck, life demands hardwork etc etc, but tbh I am now at the peak point of being stressed and now I don’t even know I would do in the future.
