CW: Possible ED - mentions reactions to food.

I'm only new to learning more about my diagnosis. I was diagnosed when I was 19 but I am now 26 and have had my diagnosis confirmed more recently but resources are slim in my country (DBT isn't really recognised here and only done in workshops).

I've noticed that when people talk about splitting they often refer to relationships and stimulus that comes from verbal or physical interactions with other people.
While I have experienced this I also experience very similar emotions and responses from other stimulus.

Like whenever I have a food order go wrong or if I make something bad, I get completely irrational. I'm very specific about food and I always have been. It's just so stressful that I lose my appetite and sometimes even cry. I look back at my behaviour and it really is almost like a tantrum. I really can't stand it and there seems no outlet for it because it's so specific. (Furthermore I do not react this way around servers or staff it is usually from take-out or my food I make myself)

I'm just wondering if this kind of splitting happens to people with BPD or if it's specific to people with OCPD and that I would have to go back and review my diagnosis with this in mind? Just wanting some similar experiences or opinions if possible.
