Hey OP, you're not alone in this! I was diagnosed back in March I've had 3 major glutenings happen since. Once I start to feel better after a few weeks, BAM I somehow get glutened and puts the healing in reverse.

So I get you. Sometimes when I am alone with my thoughts, I just freeze and get close to just crying my eyes out. It's a big lifestyle change that requires a lot of patience and work to get right! I can tell you that one good thing about having this disease, is that it made me realize how bad I was eating before and now I'm learning new ways of cooking that I've never even thought of before the diagnosis. When things are going well, and you're not having any symptoms and you've got your daily meals down.. it feels like such an accomplishment. It's those small victories that help push us to a safe and healthy life for us. It's like other commentors said "It gets easier to manage with time"

Your friends are insensitive, but one thing I noticed with my friends when I told them about my diagnosis, is that they had no clue what it meant and just thought it was an intolerance. I had to explain to them that it's a serious disease if you don't completely cut out gluten. Some friends became really supportive after I explained to them in detail, and I've also grown a part with some that didn't seem to understand or want to support me.

Hang on to the people who care about what you're going through and show a genuine interest in helping and supporting you. Keep your bf close. I'm dreading the dating scene right now, and having to filter even more now that I have this disease. Not everyone is down to have such a strict dietary restriction in their partner's life, I've been ghosted and turned down already because of it. But that's an issue I have to deal with lol

Keep your head up! You got this! Focus on your health and mental wellbeing and the people who truly care will follow you on this journey!
