Assalamu alaykum,
Sister, of course you should read salah. In fact, salah is the one thing you should cling on most no matter how low your iman might be feeling. Some scholars even regard it as the criterion between someone who believes and someone who doesn't. Salah is a unique gift given to this ummah, we can worship directly to Allah swt, and you don't want to lose that on any count.
Sometimes, it can be difficult. Sometimes it can feel inconvenient and like a chore, sometimes it feels like it's having no benefit, that happens to everyone because iman is a dynamic, growing part of ourselves, it can fluctuate. Even the Prophet (peace be upon him) said that iman is like a piece of clothing, it can wear out with time and we should constantly renew it.
Even if you don't feel like doing it, force yourself to. Force your heart to submit and one day it will see the true beauty in submission to Allah swt, but only if you let it. Salah will certainly renew your iman, but you have to allow it to penetrate your heart and truly realise that you are praying to Allah swt. And never think it's not helping you, Allah swt has promised that He will respond to our calls, but only if we call out to Him. If something good is withdrawn from us in this dunya, it'll be returned in the akhirah, He is completely Merciful.
And when My servants ask you, [O Muhammad], concerning Me - indeed I am near. I respond to the invocation of the supplicant when he calls upon Me. So let them respond to Me [by obedience] and believe in Me that they may be [rightly] guided. (2:168)
