Focusing in the now and the letting go of attachments may not be easy for many people.
However, practice makes perfect.
Meditating is a very good exercise to help you to develop a focused, disciplined and calm mind
so that you are prepared to face the reality.
Meditation is not religious.
Anybody of any faith can practise it.
It is just a mental exercise to help you to develop your mental and emotional potential.
It is effective in training you to be able to let go any attachments and negativity.
When you do meditation
you are focusing on a subject in the now
Thoughts of the past memories, random inner chatter and negativity might arise while you meditate
so choose to let go these attachments and stay focused.
It is not easy at first to let go while meditating but with consistent practice
you will benefit a lot from having trained mind and emotion.
There are many kinds of meditation such as breathing meditation and love meditation.
I would recommend you to do love meditation consistently as it is very practical and helpful.
Love meditation is an exercise to cultivate the emotions of higher spectrum while developing your ability to stay focused.
Many people who practise love meditation consistently find that people around them become very nice
and they encounter positive events in life very often.
That is because they choose to embrace the higher spectrum of emotions when doing love meditation, which cause them to attract positive events in life.
Meditation is a very healthy exercise for your mind and emotion.
I hope you will benefit greatly from practising it consistently. 
Peace.
