No worries.
firstly on the drink front its crucial for you to increase this, as it helps your body digest food, and its got for your skin and everything, you are seriously dehydrated, which will also make you feel run down. I try to have a pint glass of drink sitting around all the time and just keep drinking some, wether its fruit juice (helps with your 5 a day) or if your not a fan of water have something like ribena in it to make it taste nicer, plus contains added vitamin C. Try to drink between meals as opposed to drinking loads with meals too, as this dilutes your stomach acids, so it takes longer for your body to digest a meal.
Slightly concerned about these cheese tosties, not a great thing to have. Have you thought about panninis? Ihave them toaste with healthy living motzerella (way lower fat than hard cheese, and with a bit of chicken breast and red oinions, or mixed peppers, turkey bacon etc.
When it comes to dinners are you haveing veg with these meals? If you have something like burgers, try to have it with a bit of side salad. Also you have had red meat as your dinner both nights, avoid having red meat as your main dinner more than 3 times a week, it takes weeks for your body to fully digest it. Try to have skinless chicken and fish. So many people on this forum seem to eat very little fish!!!!
Keep going though, I will keep having a look and see if I can see more things to help as you go along.
