Thsi is the hardest thing i have ever done. Reading through some of the struggkes people are having gives me HOPE.... Been on wk 1 for a few weeks now. Need to push myself although losing the will. Feel out of breath very quickly. I don't know what to do and it makws me feel upset and tearful that i can't do this. Really demoralised. .. Not happy and I know only I can make the change.
