Hi, i understand what you i mean as i also feel disconnected from God but i feel like sometimes go the way we and that is just life. your prayers were not directly answered but Allah may have answered them in a different way, maybe your new plans will be so much better than the ones you were set on previously, but because you don't know what will happen you are left wondering if you are not worthy and that all of your efforts are not seen. I went through something similar to you as i also wanted to study medicine and prayed so hard and was consistent with tahjudd and still my ucat was low and my grades were low despite my efforts academically and within religion. but now i am ind of grateful that it went that way because i was so miserable throughout all of it but couldn't recognise it because i was so focused on reaching my goals in the timeframe that i set for my self because to me it was the only way. i would sit praying crying until i felt sick and nothing would change, i would wonder if Allah was ignoring me but i realised that i may not get everything i pray and work for as that would be too easy. and even if i don't get them there are other wins that i have and that i am getting. My advice would be to keep having faith and still try to keep up with prayers because you never know when you may need them. Try to have faith that good things will come maybe not in the exact way that you expected but they will come. I know first hand that it is not easy and it is difficult when everything is falling apart despite the fact that you are trying with religion but all i can say is continue to try and that i inshallah great things will happen to you. also your grades were amazing they may not have been what you expected or worked towards but none the less you did well and you can not change your grades now so just be proud that you actually did that and smashed your exams.
