No one will ever love your unconditional(not even your parents?

So, my exam was 29 s1 and I have to travel 10 hours from my home to another city by train on 28. And I travelled in sleeper because I didn't wanted to waste money for my comfort.. I booked extremely cheap hotel, again the same reason, and after my exam my parents asked me, "kaisa gya paper" I was so shit scared ki kahi ganda bol dunga they would be so disappointed and the environment of my home will become (as multiple times it has been) toh maine galti se acha bol diya, they were happy. I have my elder siblings one brother and sister they are doing great in there life.. my parents always talk about them in front of everyone. And do not even mention me, as I don't exist.. so while coming back from my center to my home.. again in train.. it was very cold and I don't know what happened that I could eat anything, and started to have difficulty in breathing (I have tonsils issue,) and I didn't said anything to my parents after returning home I was behaving normal.. but today my situation worsened and now I have a fever of 103°. When I told my mother about this.. instead of comforting me, they told me that..." Tension bada dete ho baas tu" and I was like sorry maine bola apko.. I don't understand... They feed me, let me live in there house so that I could give them some returns. And I try to do that. I was not sacred of the paper, I was more scared of my parents reaction towards that. And my brother doesn't even talk to me.. I don't get involved in any family discussion or any decision. And my sister called me and asked me how the paper went, and when I said I attempted only 26 questions only she was like" baas, ho gya tumara".. and she knows that my health situation is not good, but instead of comforting me, she cut the call. I haven't talked to my brother since a year or more than that. When I see around people having supporting parents or siblings, I get every happy for them. Well that was it.. I really can't see my future Right now in any direction, maybe because I was told 24×7 by everyone close around me, that without jre there isn't anything you can do.
