What you do not know is your pain is giving you the strength. It's hard, it's painful, it's irritating, it's depressing, it's frustrating, you want to get rid of it right away but why are you still alive? why are you still fighting? why are you still breathing? it only means that that pain is giving you the strength, it's there for a reason, it's there because it's making you a better person. It's already in your life for a very long time but it can't kill you. You feel weak sometimes but the more you accept it the more you get stronger. Your mental game is improving, your tenacity is improving, every time you overcome it... you gain confidence, you feel proud of yourself.
So let that pain remain in your life for as long as it wants to, never despise it, never get emotionally weak because of it. Don't talk about it, don't complain about it. Let it remain in your life because the moment you accept that pain, it gets weaker and you become stronger. Stop wishing for a perfect life, wish for more strength to endure any kind of pain. It's ok to feel it, it's ok to have it, it's nothing it's just another feeling. Keep going no matter what, push forward as hard as you can and pain will go away. Work, ignore the pain and focus on your goal. The side effect of focusing on what you really want is getting what you want and not feeling the pain anymore. You will never even notice that the pain is gone already.
Feel it little by little, slowly move forward, focus on doing something, focus on appreciating that you can move. Don't worry about pain, it's not here to stay forever. Be happy because that pain is giving you the power, it's giving you the strength, you just don't know it because you don't want it. But if you will accept it with open arms then that pain will be converted to energy. You can convert any kind of pain into power, use it as a motivation, use it as a fuel to take more actions, let it make you mad and do the right thing, let it be a reminder that you need to become better than yesterday.
And the truth is... you can push forward despite of pain, you can still live a normal life even if you have it. It's not there to make you weak, it's there to make you more alert and appreciative of your life. It's only making you harder and tougher and wiser in life. Don't give it another meaning, don't give it a weak meaning, see it as a blessing. It's only testing you, it's only preparing you for a bigger challenge. There is no pain that you can't overcome, there is no challenge that you can't face. So open your arms to everything, open your mind and always be ready for everything that may come. Let that pain live in your life for as long as it wants but never complain about it, don't be proud if it, just endure it. Don't brag about it, don't use it as an excuse, don't use it to get sympathy, don't use to to have self pity, just feel it and watch your life transform with it, watch yourself grow and enjoy it as much as you can.
