Coping with chronic illness and nausea. Any advice?

In September I was taken to hospital with breathing difficulties. I was told I’d had a heart attack caused by a blood clot. I was critically ill and transferred to ICU. I will spare you the details but after a few weeks in hospital I am home with myDH is caring for me as I’m very weak, not very mobile and taking a lot of medication. I have had gastric problems for years but the medication I now need for my heart failure are causing terrible nausea. In particular I’ve just been switched from Warfarin to Apixaban and the nausea is awful. I’ve lost a lot of weight and, although only about 8/9 stone pre-illness I’m now just over 7st. I’ve had good advice from the dietitian but because of the nausea I’m struggling to get food down. I get extremely anxious about all this, which obviously isn’t good for me. Has anyone suffered similar nausea issues with medication and is this how my life will be? I don’t like leaving home due to fearing being sick. The only time I go out is for hospital appointments. If I have to expect to have to live with the nausea, does any have any advice as to how I can cope. Sorry this has been a bit long.
