Confidence and self-esteem affect far more of our lives than we sometimes realise. They can influence the relationships we choose, the opportunities we pursue, how comfortable we feel around other people and, perhaps most importantly, the way we speak to ourselves.

Losing weight can be frustrating, particularly when you feel as though you already know what you should be doing.

.Brain fog can be surprisingly frustrating. You know what you want to say, but the word won't come. You walk into a room and forget why you're there. You read the same paragraph twice without taking it in, lose your train of thought halfway through a conversation or find yourself struggling with tasks that would normally feel straightforward.

There are few things more frustrating than being tired all day, looking forward to going to bed and then finding that sleep simply won't come. You turn off the light, get comfortable and wait. Then your mind starts working. You think about tomorrow. You replay a conversation from earlier. You wonder why you aren't asleep yet. You check the time and start calculating how many hours of sleep you'll get if you fall asleep now.

You see a spider and your reaction is immediate. Your heart starts racing. You may freeze, move away as quickly as possible or call someone else to remove it. Even after the spider has gone, you might find yourself checking the room, wondering where another one could be hiding.

Driving anxiety can make even an ordinary journey feel like an ordeal. You may be perfectly capable behind the wheel, yet find yourself becoming tense before you even start the engine. Perhaps motorways frighten you, busy roundabouts make you panic, or you worry about driving somewhere unfamiliar.

A panic attack can be frightening, particularly when it seems to come from nowhere. Your heart may race. Your breathing may change. You might feel dizzy, shaky or unreal. Some people become convinced they are going to faint, lose control or that something terrible is about to happen.

Imposter syndrome is the persistent feeling that your success isn't real — that you've somehow fooled everyone into believing you're more competent than you actually are.

If you've spent years going on diets, losing some weight and then gradually putting it back on again, the thought of starting another diet can feel exhausting. You may already know what you're supposed to eat. You probably don't need another list of forbidden foods or a complicated meal plan. What you may need instead is a different way of looking at weight loss. In my experience, lasting change is often less about following a diet and more about changing the everyday habits

We’ve all had those moments where we plan to exercise, but when the time comes, the sofa looks much more appealing.
