IDK if this is the right place or not to ask this but i need to do it anyway.
So before getting to the question here is some background about me.

SO I am a 17yo high-school student from India.Computer Geek (But i am open to any kind of knowledge and i keep reading about stuff ) Highly interested in politics and a wannabe entrepreneur.

So Here is my question

So there are people who talk to them self but its little different in my case

I dont have convos with myself but I talk to other people.Like i imagine being into an interview/seminar and i am answering the questions or i am giving a speech for a political campaign etc etc.So i am always talking to other people

I dont have good relation with my parents (Personal Issues) and i have a GF ( ps -- she is my life's first and only crush ) i love her alot and i love her family too...more than i love my family..so sometimes i imagine that we both have grown up and i am with her family..spending some quality time..helping her mother in kitchen and things like that...cooking for them and all...so it keeps hapening..and by "imagine" i dont mean that i force myself to that state of mind..it happens automatically..like i am studying and talking..cooking and talking...there is not any fixed situation when this happens...it happens anytime...sometimes i am just sitting in the chair talking to myself and my legs automatically start walking towards the bathroom and then i am inside locked myslef in standing in front of the mirror and talking and my voice is not loud..its loud enough so that only i can her myslef..even my lips dont move when ther are people around me .SO is all this normal...or should i be worried about it?

[PS- i prefer being alone..i dont go out..i am always in my room studying or coding...maybe this could give you some idea about me].

Thanks
