First year grad student having doubts

I'm a first year grad student at a good program and I'm suddenly thinking I can't wake up every day and be an SLP. We're heading into our first clinic rounds and I'm not sure if I should pull out before I've sunk too much money into this degree that I might not use. I studied slp in undergrad and did my observation hours at my school's clinic observing SLI, artic, and aphasia patients. I didn't find it super interesting, but it also didn't make me think I wouldn't be happy as an SLP. Unfortunately my undergrad degree is useless without a master's degree. I'm fine completing another master's degree but I need help deciding if I should stick it out or leave before I rack up a lot of debt.
