So at my highest weight I was 509. I had become a complete recluse at that point. Other than going to my job I always had an excuse to not go to any of my families gatherings, my kids school stuff, anything. I understand your hesitation especially in social situations where everyone is looking their best. Personally going out into these situations was like shining a spotlight on everything I didn't like about myself, and so I avoided it all. Post surgery I still find myself thinking like that sometimes. It's a struggle, to balance those negative voices in your head. I can tell you I regret everything I missed out on. At the same time, it probably wouldn't have been good on my mental health to try and muscle through it all.
It's a journey for a reason, only you can decide what your ready for. What I learned about the process is that my true friends were patient and were happy to wait for me to be ready to take the next steps.
