How hard is it to transfer from a community college to Lehigh?

My best chance for Lehigh is early decision this January. I am very conflicted on throwing away this higher rate of acceptance for what looks like a highly competitive transfer rate from a CC. I don’t think I could get in without early decision aiding me, but I am running out of time to think about this. I am afraid my mental health is not stable enough right now to go to Lehigh, but I don’t want to take a second gap year. I could really use some advice. I already know my major-- physics.
