Feeling better than yesterday!! still ate too much and some thinspo

This morning I woke up at 9:30am, my thighs and arse were soo sore, it still is thanks to the body pump class I did last night, I didnt think I actually worked out lol squats and lunges hurt anyway I thought 9:30 was too early to be awake, I would of ate more than I wanted to so I went back to sleep and woke up at 15:35pm got outta bed had a shower weighed myself (78.4Kgs) forced down chicken parma carrots and zucchini for mums sake I couldnt purge coz we were in a rush to get to the zumba class which we missed anyway so went to the gym treadmill 30mins (180) elliptical 45mins (400) by then my legs were just too sore I could barely walk so we left, got home and made B a sandwich and heated another piece of parma for him and had a bit :( then had a fruit salad with 2 spoons of yogurt according to calorie king the parma i had for dinner was 757 calories add like 150 for the extra bit i had, the veggies 52 and the fruit salad with yogurt 143.
Argh just makes me want to pull my hair out, i really dont know what my problem is i just cant stop eating!! no matter what i say i never do it or stick to it! i missed my diet pills again today cause i just forgot about them, they've been giving me the worst mood swings by the way 1 min im really happy the next i just get so mad at every small thing people do or say then i get sad and cry over the stupidest things and i havnt had my morning lemon and warm water either. last night i cried myself to sleep I just feel like such a failure, one week i do really well then the next i just mess it all up and gain most of it back its pathetic, I know how happy it makes me when i see smaller numbers on the scale yet i continue to stuff my face.
I can see this entire week being a bad, shitty, weak, binging, horrible, weight gaining week, I've gained 1.4kgs from the weekend + yesterday and today. whats with me these days?? I plan to stay up all night in order to sleep all day tomorrow i know that sounds bad but i need to resist food, then i'll wake up at 4ish have tea water and MAYBE a fruit of some sort then go back to sleep, if my legs feel better i'll go to the gym if not i'll have a day off with some deep heat by my side, it hurts so bad I cant stretch my leg out fully or bend my knees too fast or climb stairs or move quickly or even sit on a chair without my thighs hurting, it was the first time i did it so i used light weights 1 - 2.4kgs thats what the lady recommended for my first time so it wasnt heavy or anything and we did warm up and cool down and stretch etc anyway heres some oo the thinspo I put on my ipod to keep me motivated on the go
