Need Help As I Seriously Don’t Feel Liveable Anymore

So basically I am a 18M , my life used to be quite good while I was in the last days of my school but after that my life has literally been hell and I really don’t feel liveable anymore. 2024 was the worst year of my life which has been the main reason for all my sufferings . Since I lost all my school friends , I haven’t been able to make new ones in my college because of conflicting moral values and them already having friends whom they already knew from the past time . So it was highly difficult for me to adjust between them and till this date I don’t have any good friends and I blame my parents for all this misery as I personally had the desire of going abroad as they had already sent my sister to study abroad in 2019 and my parents initially supported it but after my board exams got over they reversed their decision of all a sudden and promised me that they will get me into a good college in India by their own and they just told me to give all the entrances and neither did they fulfil that commitment nor I could go abroad and because of all this I am mentally disturbed as these thoughts always trouble me when my mind is idle because I feel if I did something which I wished to do then I would have not faced such a problem and because of me being mentally disturbed I tend to share the same with my father as he didn’t let me do what I wanted at the end and he risked the 4 years of my life which are the days which people remember of their college life . My father on the other hand just cares about my mental peace and just tells me to not talk about this thing but he never thinks from my point of view that what all do I have to go through just because of his one small promise and his decision of not sending me where I wanted to go . I hope there is a little humanity left in people if there is then please help me out .
