struggling

Hi every one! I am realy struggling at this. I am trying to figure out how to work these pages and how you guys got pictures,weight gage,ect.I feel a little overwhelmed.I had lost 26lb in six weeks onley gaining 7 back in 7 mo.But then ten in one. I didnt think i would gain it all back and it would be so hard to get back on track is even harder.
