Also vouching for a bonding bag so you can easily spend time with her while doing other things.
I hate to be that person, but I also want to mention that it doesnt make you a terrible person if you feel as though she may be better of elsewhere. Hedgehogs can get messy, and not cleaning their cage frequently (and their wheels need to be cleaned every day!) can make for some very unhygienic living situations for your pet. Sometimes things dont work out, and I think its important to realise that thats okay - and if you find yourself struggling again, it may be worth considering rehoming her.
Getting her a new enclosure and spending more time with her is absolutely a great start; perhaps setting an alarm to spot clean her every day, so you dont let it build up and become an even bigger job to tackle in one go, would be beneficial for you too.
