First, I hope you start feeling better soon Aaron - I know exactly how you feel !
Second, from what I can see, if you can't remove the wing, by very gently and slowly bending it up and down, and at the same time working a scalpel blade or razor saw blade along the joint. to break the bond, then the following might work.
On the underside, it looks like there is a slight step. This can be carefully filed with a jeweller's file, then sanded with fine grit.
Forget about the panel lines for now. The upper joint, and the sanded lower joint, can be filled with repeated applications of PVA, allowing each to set before applying the next. If too wide for this, then a bead of CA run into the joint, and allowed to set, followed by more if required, then topped off with PVA could sort it.
Use a needle or sharpened cocktail stick (wooden) to apply both CA and PVA. The final application of PVA can be smoothed off with a wet finger tip.
Any missing panel lines, personally, I would ingnore - they probably won't be noticed anyway. But, if you really want to, they can be carefully etched with the tip of a scalpel blade, to give just a suggestion of the continuation of the line.
Bear in mind that, on the real aircraft, most panel joints can't be seen until up close, a few inches away.
Hope this helps.
