Assalamu alaykum sister,
It seems like you are suffering from waswas, which is the whispers of shaytan. Islam is a religion of mercy and ease, not hardship. Allah tells us in the Qur'an that He wants ease for us, and through studying the teachings of Islam we find many examples of this. So you have to keep things simple and fight these whispers. Shaytan doesn't want you to succeed and wants you to give up and stop praying, so you can't let him win. Ignoring the doubts is actually following the teachings of your deen, not neglecting it. You have to follow what your deen teaches you and that includes turning away from such doubts. May Allah make things easy for you and protect you, Ameen.
