Am I sinful for something I am not in control of?

Assalamu alaykum wa rahmatullahi wa barakatuhu, I hope all of you are having a blessed Ramadan Ameen I need advice on a topic that has been on my mind for a very long time. I think I may be on the spectrum and this has been very hard on me, I keep thinking of it over and over again and have all the symptoms which match with people of this disorder. I am very depressed and don't know what to do. My Imaan is lower than ever, infact ever since Ramadan began, it went down to the point where I struggle to pray the five Salah now. I feel like I can't open up to anyone and think that I am doomed because Allah has removed Salah from me or something. Please note that I still go to school and external factors are also affecting my Imaan. For example, my kafir teachers do not allow me to wear the abaya and this grieves me a lot, especially since I go to a mixed school (classrooms are separated though) even though ma sha Allah I score great marks in tests and etc, there is an emptiness inside me. Teachers like me but my peers don't because I am rude to them even though I don't want to be. At this point it feels like I have no softness left in my heart because I fail to sympathize with others and struggle to speak about my feelings, I keep saying stuff I don't mean too. The constant mood swings are getting to me. Please bi idhnillah provide me with support on what i should do. I also have very bad anxiety which makes it close to impossible to be in public. In summary, I want to know if i will be held accountable for my actions if I actually end up having autism because I have no evil intentions whatsoever. My imaan is lower than ever and I don't know who to speak to it, I barely have friends and those that I do have I fear they will judge me for my condition, I know I may misdiagnose myself but I had a feeling that I have ASD and my parents hid it from me, that's why they act differently with me than my siblings :( Jazakumullahu khairan and may Allah accept our deeds this Ramadan.. Ameen
