Hello Alamore
It's a shame that's happened to you, ive never experienced it myself. However I've got some insight uponit based on my inference of what the situation is. First off, what exactly are you carrying in your pack? Could you possibly discard any items of low importance?
Another suggestion, based on your enchanting skill, would be to imbue some articles of armor/clothing with some Feather or even Strength. Feather is very useful for any low Strength character like yourself. Every point of Strength however grants an extra 10 WGT to your available pack, but my guess is that a point of Strength costs more storage points than that of Feather. So the desicions are up to you on my suggestions, or you could wait for some more from our other wonderful forum members.
