Maladaptive daydreaming

Hello guys I am a 19yr old (F) and I am suffering from maladaptive daydreaming. I just start talking to myself randomly by making scenarios in my mind related to my career , future etc. I have been into this for more than 4 to 5 yrs. Earlier I didn't realise that it was an issue until it hampered my ability to study and I remain absent minded not able to focus on anything in my life , it's a crucial point for my carrer but I am not able to work on it. This makes me feel left out and cut off from the society.I desperately want to get rid of it. Pls help me out
