Every individual is blessed with different kind of character. Some are way too outgoing & some are aloof kind of personalities who enjoy their solidity. We all face different kind of phases throughout our life, there will be countless happy moments and some junctures as well. In my opinion an outgoing person will face it more efficiently than the detached ones.
People who enjoy their solidity wouldn't talk much to other people when they will feel low but they'd endeavor with it their own way. Sometime it'd work and sometime it wouldn't so talking to someone else during that situation might be a best option and can make you feel much better.
This is a bit sad, everyone always has some good, funny and sad or scary memories, so you don't need to cling on the bad ones but remain yourself on the good ones. You're in good health and this is something really great because there are many people who don't have a good health. We all are running after something every single day, we're being objective most of the time but when we try to be a little subjective we realize that actually, we have so much!
Life always tries to balance things, we lose and gain something on daily basis so we also need to maintain the balance with memories too. Let the painful memories fade away and make the space for new ones, good ones. It's true that some memories are knitted well with you that they won't fade easily but at least try. When you're travelling or sitting at a restaurants and looking outside, just look at someones suitcase or at a parked car on the road.. concentrate on it and put all your sad memories into that suitcase or the boot of the car.. Yes! do it, look at suitcase or the car until it's gone, you don't know where it is going but it will go away and will lose somewhere in this universe away of you. If it's coming again thinking about it, just remain yourself and don't have it. You don't know where it is, it's gone. New positive things need space to come so send the painful ones away.
Whenever you feel low, talk to someone available at the very moment, it may work miraculously. Just talk yourself out when you're low and you will see the light coming close to you.
