While working Aircraft X ZZZ-ZZZ1; I became concerned for the health and well-being of my flying partner.  She displayed numerous symptoms of severe illness including: persistent coughing; sneezing; shortness of breath; weakness; and sweating profusely.  Prior to starting the service; I witnessed [flying partner] remove her tote bag from the galley cart and take several pills.  [Flying partner] then had difficulty pushing and pulling the beverage cart with assistance.  It strained her and seemed very difficult for her to speak with customers; so I had prepared a sign in blue marker that read; 'What do you want to drink?' and listed beverages.  After picking up trash; [flying partner] repeatedly placed her used gloves on top of the galley counter.  Upon descent into ZZZ1; I noticed the orange strap at door 2R was not attached and reminded her to affix it.  At that time; she was coughing and was no longer wearing a mask at all.  I expressed genuine concern for her well-being and was uncomfortable flying with someone who appeared so unwell.
Flight Attendant reported another Flight Attendant was ill during the flight and not able to wear the face mask at all times; especially when coughing.
