Help with young mango tree!

[MangoMeCrazy]

Hello there! I have a mango tree that I am over wintering inside in North Carolina. The leaves are turning brown and curling in. I clipped a few of the unrecoverable ones but it's still growing! I water it each week which it seems cool with. It seems to be sprouting new growth as well, so I'm optimistic. I really don't want to lose this plant, I raised from see when I got it from Kroger . Any help would be appreciated!
