Expected something different, something that would make me change my thoughts or rethink possible outcomes. Tearing at nails won't help them grow and over analysing situations won't help you with any problems. Find more to pick at, more examples to add to your opinion. We learn more from apparent failures than from supposed successes, it pains us to dwell on disappointment. Don't get too deep, you'll find yourself stuck, looking up from the very bottom. There's no point in listening to another persons standards or another persons judgement of you, will you really change? No one wants to and no one needs to. Variety is what takes us all on different journeys. The chance encounter with complete strangers, any one of them can change it all.
Don't become accustomed to these emotions and feelings. Frustrations and anger have to pass. This won't be like this forever, better things in the next few days, it's already started. It started months ago. I'm here to help and i'm here to put the smiles on the faces. You don't have to prove anything to anyone, don't apologise for things you've always wanted to do. You won't win friends by pretending to have a low opinion of yourself. Teach yourself something new, high regards of others who make you think of things you've never thought of before.
