Make I also really struggled with the impact on appearance, went from very attractive on starting chemo to totally trashed after it and a years Tamoxifen. Hair trashed , boobs trashed, and went from normal BMI to overweight. I had to avoid mirrors and cameras. It shouldn't matter but its just another thing to add to the list of awful things that have happened.
What has helped has been swimming and get that up to 3 times a week about a mile a time but any exercise you can do helps and 3 to 5 hours cuts reoccurrence risk 50%. That has helped hugely physically and mentally. Then being kind to yourself which I struggled with but am coming round to, your body has been through a lot and it will take it a while to recover. Once I realised I had put on weight, 14kgs up 😱I added that to my list to start tackling . Lost 4kgs in a month but have just stalled last month. So still 10kgs to go and found it harder with the cold weather and dark and everything is about food. But my hair is getting better, still another year I guess before will be as before but it looks like a style now, well almost. Breasts I find the Ameona swimming ones helped which wear all the time, obviously its rubbish still but you at least can hide it. Take a wellwoman 50. I am not back working as have savings and esa and lovely husband and have SN son who requires a lot of input, DD doing A levels and reconstruction to go. But I do generally enjoy not working and apart from the meetings etc just go swimming 3 times a week, to events, on holiday so its quite pleasant really and do work on the house. I would just start with something you enjoy and keep going.
Welcome @MissMarplesNiece That sounds really tough. Can you get advice from your oncology team on how to feel better. Exercise has been the biggest thing for me but you'ld need specialist advice to see if that's possible. If not hope you can find something else you enjoy. It is strange its like your life was suddenly turned upside down and you make a new one and its working out what that is.
We will get there, one day at a time and if one day doesn't go to plan just be kind to yourself about it. Floof also helps me so much, my trilly, permanently happy boy.
