TW: eating disorder... would you say this is an eating disorder?

I have moments when I don't eat breakfast or lunch. I've never liked eating breakfast anyway since I was 10 years old but I have moments when I hate eating lunch. Like right now I hated how much weight I puted on during lockdown and being in a 2 year relationship. I've always been skinny so my clothes not fitting me has been tough especially since everything is expensive now. Anyway I go through this thing when I don't eat lunch as well as breakfast so I was wondering if it was an eating disorder?
