Good grief! Look at your signature! You've done an amazing job. You hit a big bump in the road, don't let it derail you mentally or physically. If you were working out an hour and a half
every single day, maybe your body is telling you that it was too much! Everyone needs a rest day, and it sounds like you had very little reserves for fighting off infection. Good choice on staying home. Coughing non-stop and workout shouldn't happen in the same sentence
Let your body get better. Choose healthy foods and practice maintaining. When you are better, you can get back to the gym. Being sick makes you feel crummy enough without piling guilt on top!
