Tara I felt the same when I had a break from it for a few weeks. I kept trying to start SS and just managed a day or two and thought I couldn't stick to it. You said you know it works, so you CAN do it
Have you tried taking it one day at a time? Maybe try not looking at the long haul but just think "Today I will SS 100% then tomorrow if I choose to eat I can" when tomorrow comes, try the same again.
Then you aren't forcing yourself to do it, you are giving yourself a choice. One day at a time might work. If you succeed 100% for day 1 then maybe you will think "It wasn't so bad I can do that again" and CHOOSE to do it not feel pressured by yourself to do it.
Before you know it you might be on Day 5, well and truly in Ketosis and feel full of enthusiasm to continue. Might be worth a try!
Good luck & you can do it :hug99:
