Can you please drop your 2 cents?

I recently started my first job, I'm in my early twenties and I think the pressure is ALREADY getting to my head now. I have a job, yes, but I can't see myself having/saving enough money to buy a decent house and plan a future even after a decade's time. I feel so stressed to even think of dating a woman, how would I even think of it when my mind is freaking out and screaming about my career and settling? I'm so stressed about all this, I can't even imagine myself enjoying a weekend, planning a trip, etc. I feel like I'm not doing enough and even though I schedule some time to upskill, I constantly feel I'm not doing enough, even after a burnout. My self confidence is tied to my income and my contribution level and I'm definitely a mediocre compared to many freshers out there. I know hardwork and determination and bla bla can get you to places, but I'm scared about my mentality and how my attitude is shifting towards negativity. All these years, I've struggled a lot, I've seen a lot of 4AMs and spent a ton of sleepless nights, only to reach a below average level. No effort of mine has given me a positive result. Struggled so hard, prepared for a interviews so much, only to miss the placements due to healrh issues. Scored great in mock tests only to break my leg and skip the actual exam, etc. you get my point. and I'm so tired of this, I want to cry, I'm not even able to. I feel like I'm running underwater. I feel so frustrated and burnout. I'm worried, my go getter attitude and my mentality is slowly giving up on me. I feel like a failure even before I start. I think I'm just born with too many expectations on my own self that every passing day, I only dream of sleeping and not waking up to this mediocre life. With my own will slowly giving up on me, I'm clueless. Why is adulting so hard? Can someone help me out like an elder sibling? What am I missing here? When will I even make my way through this gamble of a life and make it big? Big enough to contribute positively and drive an impact? How do I stop giving in to this pressure? What the hell is happening? 😭😭
