Bit fed up if I'm honest (will be swears)

Incase you hasn't already seen, I had what can only be described as a COLLOSALLY shit 4 days. I barely ate, I barely drank, constant panic attacks, constant n*, stomach pain, endless arguments ect,just horrible and more than anything very depressing. Today was better. I has breakfast and a few light snacks and was feeling good and even managed to make it to an interview, and after my aunt and I went to have a meal. I deliberately chose something off the light bites menu because I knew eating anything too big would just make me feel like absolute shit. I got something that was actually really nice, it was these bits of sweet potato with cheese and bacon and some spring onions and other stuff with a cabbage side salad (I also got some chips, for the Americans present I mean fries but big ones). Was a little nervous because the chips tasted.....odd and that made me think I was going to v*, but my aunt tried one and agreed and said it was the oil so I finished the meal and felt positive, then I went home had some chocolate and also enjoyed that. It's now about 1am and I feel honestly rubbish and it's just horrible. I have a headache behind my eyebrows, in my temples in my jaw and my neck and I still feel very full. All I can think is that I'm going to v* and it's just a bit much. I don't want to fall back into that spiral
