I think with advanced technology, people are now changing to other social media channels. Not to mention, Whatsapp is now almost the same as Facebook (even though its one company), people are more active over whatsapp and other messaging tools than FB.
I think facebook has not evolved as much as it should have, it is becoming old and boring.

Maybe you should find out why she left in the first place, maybe there was a misunderstanding. I wouldn’t go back. The same thing happened to me. My ex left without saying a word, its been more than two years, but I’ve finally learnt to let go and moved on. You will always love her but is it worth it?

Sometimes you just have to give yourself enough time to realize weather something is really worth the effort or not.

Lots of exercise, healthy food and a good support system.

By lots of exercise I don’t mean going to the gym everyday, but often, also get a trainer to assist you. Yoga as well as meditation also helps alot.

Healthy foods doesnt mean only vegetables, meat has lots of protein, but if you choose to go the vegan way then that’s okay too. We balance out diet differently in our household, we eat homemade food everyday, these include vegetables and meat products and once a week (usually Saturday) we have takeaways (our cheat day). We also don’t drink cold drinks as often, its mostly water or fresh fruit juice.

And lastly a good support system goes a long way, make sure you have people giving you positive vibes and helping you. If you feel negative and don’t have a good support system then it will negatively affect your body, making you depressed and feeling worthless.

Hope this helps!
