I think there will be some moment in your life where you feel void and alone.
Though you are surrounded by your partners, friends, and family, I guess there will be time that you feel no one really understand and you should solve your problem alone.

When I was a kid, I though if I have a boyfriend then I can always depend on him, that he will always understand me. But the fact is that we cannot. There will be time, when even your closest confidant cannot really understand you. It's normal and natural. It is a reciprocate relationship actually. He must feel the same about me.

No matter how happy and healthy our relationship, we are still two different entities.
Love movies, poems, songs are responsible to distort that fact. In movie, poem, song; love and relationship are portrayed as these overrated, helpless romantic that do not actually exist.

Someone that always can understand you is not your boyfriend/girlfriend. It is a robot, programmed specifically and customized to your personal demands.
I do not even believe about the soulmate thing. What I do believe that we are connected better with certain people, and we build chemistry, and we work very hard in a relationship by compromising.

At the end of the day, the only one you can really count to is your own selves.

I felt it sometimes. My spirit goes down suddenly. Things getting very hard and dark. I always (literally) tell my boyfriend about my problem and my worry. On most of time, he will help me out, give me advise, give me suggestion, and we will solve the problem together. But on some cases, I cannot even make him understand, my deepest and darkest problem. Who only myself can solved it, can get rid of it.

What I learned so far, the best way to take care of yourself and to get out of that dark situation, is to prepare our mental, our mind. When we almost give it up, said it to ourselves that we will not. When we are afraid, said that everything will get through at the end of day. Said frequently to yourselves, that you will never let anything to crush you, that you are fire and wind. That you will make it, anytime and anywhere.  Motivate your own self.

Be strong mentally. And you will be okay.
