How to deal with sadness

It just takes time to understand but still it will linger .. its ok to be sad.. its a process

But i hope you have happier days to remember in the future

If you are sad, you must be sad for however long that you feel sad. If you are tired of being sad, and feel that the time you've spent being sad has resolved, then it's time to crawl out from beneath the weight of sorrow. There must be something, or someone that makes you happy, do that.

I go out for a brisk walk and play some up beat music.
That seems to bring me out of a funk.

Get out and walk and meet people
Even just say hello to people helps

Just involve yourself in doing something, that interests you.

Can you do some things which make you happy or be with close people?

Look for someone happy and you will become happier.

After you break up with the Pedo, rouse yourself and go for a run. THAT will get your endorphins going.
