Strength to trust God through unanswered prayers and doubt

I have been praying asking the Lord to remove me from a place or remove this person because I am tempted to sin . I’ve also prayed to ask God to allow me to pass my classes this semester and it didn’t happen . I’ve been praying over my children, been praying for fresh ideas, been praying to be a better steward over my blessings, my finances, a new home. I’ve been praying these same things for a while now . I have been single and been praying for a mate for two years. Besides the prayer requests, I’ve been praying /petitioning these other request At least four years ~ and nothing ! I’m hopeless with just a tiny bit of faith left. I feel ignored , I feel that the Lord is silent , and that the sin in my life hinders my prayers being answered(not habitual sin) . I absolutely love the Lord, He’s my everything ! I just don’t understand why my prayers aren’t being answered
