3 weeks post-op Need food recommendations

Had surgery August 1, all went well and surgeon fixed a small hiatal hernia at same time. I've had no real pain and for that, I am very thankful. I am still extremely week! One week out I saw PCP and tests showed I was anemic(no surprise) and I had H-pylori-stomach infection. Until then I was able to get liquids in and close to 90 gr of protein. Put me on 3 meds for two weeks to get rid of h-pylori, Now I can hardly stomach anything. Very difficult to get liquids in. I can eat mashed potatoes and gravy, pimento cheese, and today, cottage cheese. Liquids make me sick but I'm trying to get down.....protein shakes are a no-go! I do put unflavored protein in everything I eat. I can also do pudding, yogurt, jello, and SF popsicles. I am on mushies...but nothing tastes tolerable with this medicine. I started back to college and I am a walking wimp! Brain fog, and so weak I feel like I can fall out at any time. Please suggest something to eat that might help with energy. I am barely getting those chewable vitamins down. Also eating 2 calcium bars a day. I have B-12 patches, and liquid B-12 and taking Vitamin D twice a week. You'd think Iwould be bouncing off the walls, but I'm dragging my butt from one day and on. P.S. I'm 53 years old. I have lost 20lbs as of yesterday. Happy for that but, I need to get back into my life. Thanks for suggestions! Wishing everyone else well!
