So, I constantly keep daydreaming and I am 20 years, male. I cant stop it and it is seriously affecting my personality making me weak day by day. Sometimes, I stop it, but after a couple of days, I tend to start again.
My parents treat me like shiit, even though they love me quite a lot. This is affecting me badly and I start creating the world I want in my dreams.
Live in the present moment. What you are doing is called magical thinking. And while you are doing this life is passing you by. Set goals and work towards making those dreams come true. If you don't, one day you will look back and all you will have will be your dreams. Because you cannot think something into existence, you have to stop dreaming and set goals and work towards them.
Although I'm hardly one to talk, I daydream all the time as well!
Dreaming is awesome! although is best only done at night. If your dreaming is affecting your real life then I think what you need is a focus.
Like others have said, living in 'the present' is important to keep yourself grounded. Losing focus or getting carried away by lofty abstract thoughts can often be detrimental. I have found that physical sport helps 'bring me back to earth' and get grounded again, also going out and talking with friends helps.
Try not to 'think' too much, I know this sounds odd but sometimes it's better to become more involved in the physical practical aspects of life, worrying won't really help.
Although movies and Books are great, I would tend to avoid reading too much as this can sometimes lead to abstraction from reality especially with philosophy books.
I really hope you manage get through this stage, I'm sure it will pass, we all go through similar phases it's just a case of summoning the strength to get through it. So in conclusion, do some sport, see your friends and talk to them about it, focus on the present and the practical, try not too get bogged down by the abstract.
