“I had never been this kind of sick,” Milano shared in a written message on Instagram.

It felt like an elephant was sitting on my chest.

I couldnt keep food in me.

I lost 9 pounds in 2 weeks.

And the headaches were horrible.

I basically had every Covid symptom."

She then took a finger-prick antibody test.

“I am POSITIVE for covid antibodies.

I had Covid19.”

“I also want you to know, this illness is not a hoax.

I thought I was dying.

It felt like I was dying.

I will be donating my plasma with hopes that I might save a life.

c’mon take care of yourselves.

yo wash your hands and wear a mask and social distance.

I dont want anyone to feel the way I felt.”

Both emphasized how this is still a problem.
