Lithium + saggy body

So I’ve been trying to wean off lithium cause I have diagnosis doubts (honestly I think I’m just a bit of a dramatic brat) - and at half my dose my body actually looked amazing, I have always had a little belly but it looks nice and rounded not like a shelf of fat and even my boobs and face cheeks are more lifted. Having a hard time due to stressors so stepped up back (from 450mg to 675mg) and overnight from that one dose I’m back to fugly body…. It breaks my heart my ideal body is just there but I’m struggling to shake these meds. Has anyone had this experience? My scales havnt changed just the shape of my fat
