M25 What is Wrong with me ??

I am 25 M I work out of India in good company as of now i just come over India Just Now Over here its feels good but leaving all this and going back to work feel bad or i just don't like but what to do as i am the only person of house. I feel alone and no connection as i don't have any friends or anyone i am really tried to been alone but there no way to find new partner as everyone is Busy with there life as i am feeling lonely i try tinder and all other apps but there is no response let hope for best. i am here because i need someone to understand or just know myself but its hard now a day i just don't know to approach a girl or how i can talk because never had a gf. Whenever i see the girl or attract me i feel uncomfortable i don't why !!! but when i am Drunk i talk freely as i am gonna go for date with her because i had experience as i was traveling in flight beside my sit there was girl i talked her when i landed as i was not comfortable to talk on flight because there was a lot people or i am just shy i talked with her as freely as i can but after we complete the talked i just ask for WhatsApp number and all to getting in touch but she told it was personal so i ask her for Instagram id but she give me but the request never get approve !!! It was good talk but she was not interest as i ask her to give her a lift to drop but she told no anyways
