It seems as though you may be struggling with some symptoms related to religious ocd. You might need some Islamic counselling or Islamic psychologist for that. Don't worry though.
I feel same i loose Allah everytime in my lowest phase and that lowest phase is not ending, im 22 years old and in these years not a Single dua has been answered, now ive firm believe that he doesn’t like me or has blocked me
If Allah doesn't give you what you want, that doesn't mean He hasn't answered. He either gives you what you want, saves you from bad, or gives you a reward in the next life. If you get one of the last two believe me, they will be much greater for you than what you asked for in this life. Allah doesn't have to give anyone anything, as He literally owns us. It may be that He will give you what you want, but delays doing so, for a reason that He knows as He is The Most Wise and All-Knowing. Continue in your worship of Allah and if you have intellectual doubts then I would highly advise you to visit Sapience Institute on YouTube and book a free mentoring call with them. They are qualified experts in this field of doubts regarding Islām. As-salaamu 'Alaykum brother Arshan and may Allah clear your doubts, whether He does it slowly, or quickly, however, is up to Him.
Islam is unchanged religion from allah, allah promised to preserve it till end. And Allah exists coz there should be end of chain, necessary entity/designer/creator of universe exists 100%, universe cannot just come from nothing. Islam is way of life, and guidance to all humanity from 1 and only one god, not from 3 gods, millions of gods, only 2 all powerful god exists, and he sent prophets in every era, and he sent last prophet and last final guidance book quran. And it is unchanged. Proof- we can ask any muslim hafiz, he recites the same quran. And you should read full quran by learning arabic language , or translation, or listen it's translation in your language. And read hadiths too
I have an advice and i hope that you do it Read the quraan
