Gastroparesis after virus?

Earlier this week I came down with what doctors think was norovirus, although I only had nausea without diarrhea (actually I was constipated throughout). The nausea was awful on day 1, bad on day 2, and gradually became more mild - however 4 days later I’m still a little nauseous and have developed acid reflux and an inability to eat enough food - for the past 2 days I’ve tried to eat dinner and ended up writhing in bloated misery. Could this be post-viral gastroparesis? I have pre-existing GI issues with gas/bloating/constipation but I normally have a huge appetite and no problem eating as much as I need (I lift weights, am very active in general and and have a fast metabolism - so that’s a lot of food). What can I do? Am I really going to have to deal with this for at least a year? I can’t afford to not eat, lest I give up my athletic endeavors.

Had to add a flair but looking for general advice. I feel bloated and lost.
