Turning 25 soon and it feels horrible

I will be turning 25 this month and I feel like my life is heading nowhere. To preface this, I have always been average in studies but still got into a top college of my field. In the end, I did not go towards hotel management as a career in placements but got a corporate job and I was quite happy with my decision as a 21 year old, I was working 8.5 hours and making 23k in 2021 and for a fresher it was good money. After 11 months, I switched to a early stage seed funded startup in Bangalore(they recently raised series A) as I always wanted to move away from home because my school was 2kms from my house and college 3 kms, I had been living in a small circle my whole life and wanted to get out ASAP and when the chance came, after convincing my parents a lot I moved out. Here I was making twice what I did in my last job. It was all good, got there too early(founding team), had good ESOPs, was making good money, had a good number of friends and was generally living the best of my life. Got promoted after a year as well. I asked my parents to stop working and move in with me or my brother( the intelligent one) who lives in another state and has a great job at a PSU. Despite my fathers failing business they did not end up closing it and continued getting into debt (I was unaware of how much debt it was) I knew they had like 10-15L of debt, not more than that whereas in reality it was around the range of 1Cr+. I decided to change my career path as I wanted to get into another field, so I came back home in 2024 for 2-3 months of study and finding a new job. This is where my life changed and I feel like I have undo-ed( not sure if this is an actual word) everything in my life. When I came back home, I discovered that my father has a alcohol addiction due to the severe debt that we have. This is a person that has not had a drink since '08 and before that as well it was just on weddings or any special event. There came a point in the last year that he had to be admitted into a rehab centre as he was drunk for 4 consecutive days. At that point, I was suddenly put in-charge of the family business without any experience in it at all. We sold our land to clear some of the debt, now we are in 30L range. Business went to a rented place and we invested some of the money from this into the business as well. I never wanted to go into the family business as my father always told us children that the business is not big and we should find something to do on our own which we both did. Now I am here back in Delhi since almost 1 year, have 0 social life as all friends have moved away. Go to a failing business which I am trying vvv hard to turn around and there is a little bit of hope that it might but you never know. Everything has been rushed onto me and I feel like I am losing out on a very important time period of my life as I know that my family will start pressuring me to marry by the time I turn 27 and till then I will be so occupied in making my career or working that I will lose out on so much. I have never asked for anything from my parents, I was a good boy, never got into trouble sometimes a below average grader but overall good, never had any extraordinary demands from my parents unlike my older brother. Stopped taking money as soon as I got a job and even started giving money back after going to Bangalore but I still feel that I suddenly got dealt a very bad hand. Had so much of my life planned but everything is in shambles. Reasons for the debt, grandmother got hospitalised every winter and that was a huge bill for us, sometimes even exceeding 10L+ per visit. She did not leave anything for me, my brother or even my parents, grandfather still says everywhere that hospital only costed 10-15k and "inhone kya hi paise kharch kare hai." Father has 5 sisters who took all my grandmothers jewellery and grandfather even though he had a government job, never saved anything and gave everything to his daughters. Even now those daughters are refusing to sign a NOC for their claim on our house which even though is quite small but since it is in a market area worth quite a bit. Even my grandfather has not done anything for us, just abuses me, my father and mother all day. Meri bhot G\*\*\*d fati padi rehti hai yaar, have sleepless nights too. Parents to bol dete hai chale jaa vapas karle naukri but I know that if I leave them like this I won't be able to live with myself. It is kind of an inevitable position that I have been put in which I do not like. I hate it and I hate my life now. Whenever I try talking about anything to my parents, father just says ki "humne bhi to kara hai, isme kya nayi baat hai" and mummy ka to fayeda nahi hai honestly, I thought she was the one who understood me but then, she also just starts crying. I feel 25 is too big of an age, zindagi mai ek baar bandi bani thi 20 ki umar mai vo bhi mere best friend se pyaar mai thi poore time. Kya hi jha\*tu kismat hai meri, never been able to trust another girl after that. i just do not know what to do and I feel like mera bhot bada breakdown aane wala hai because everyone is moving ahead, 2 of my friends are also getting married this year and I feel like I am going backwards, I never wanted to be here. TL;DR - Zindagi ke lau\*e lage pade hai and umar nikalti jaa rahi hai
