I just made stylistic changes to improve the flow and make it sounds natural :) Hope you like it!

There is a lot that is open to interpretation and feeling, but here is one example of some minor corrections.  Thanks for sharing!

Today I walked outside and breathed the fresh air, received the warmth of the sun, watched the ducks in a lake, but felt sadness in my personal life.

Then, I just decided to send everything bad straight to hell!

I can meet with my friends, walk everywhere I need to go, and do all of the things that I really love to do. This life is our only one. We don't need to spend it in tears while being sad.

I wish upon you bright emotions, an excellent mood, sweet lovers, a lot of inspiration, and good news!

Be happy!

Good decision)

Today, I have walked around my house; I have breathed the fresh air; I have got warmed under the sun; I have watched the ducks in a lake, yet I have also felt sadness in my personal life.

Then, I decided to tell myself to hell with everything!
* To hell with someone/something> I do not care about someone or something.

I can meet with my friends, walk anywhere I like and do anything I want. Because we just have one life to live. We don't have to spend it in tears and sadness. I just hope for a life of happiness and excitement -- one which also gives me much love, inspiration and good news!
