I’m not sure if this is a BPD thing, but I literally have no appetite ever.
I get hungry and feel hunger pains, that’s not the problem, it’s that when I notice I’m hungry or that I haven’t eaten in a while, I don’t want to eat. Nothing sounds appetizing.
I can’t decide what would seem good or what I could even tolerate.
It’s was fine for a while because I fixate on one thing for a while or if I’m dating someone, I’ll eat whatever they’re eating. 

But I’m single, I can’t afford to keep ordering pizzas that I barely eat and I have no idea what to do.
I buy myself groceries and make a meal plan, but I can’t keep up with it and now I’m accidentally going days in a row without eating because I CANT DECIDE. 
And if I force myself to eat, I feel sick. Probably because I go so long without eating, but it makes it even harder to have an appetite.

What do I do?? I can’t keep not eating.

Edit: I should also add I’m a very active person as well so I’m burning wayyyy more calories than I’m taking in and it’s starting to take a huge toll on me, which is why I’m writing this because i feel like I’m on the verge of this being very dangerous.
