I'm in love with a celebrity

i'm a 29 year old gay guy and I'm completely in love with a guy called Danny Miller who stars in a soap opera called Emmerdale. I've been in love with him for 8 years and I just can't stop thinking about him. I can't wait to go to sleep every night so I can fantasize and dream about us being together. I have over 300,000 followers on twitter but i only read his tweets and I tweet/dm him all the time. he follows me and sometimes he replies and I feel like we have a connection but I know deep down we don't. I find myself messaging him anything just to try to get a response but I don't want to get to a point where he blocks me altho he jokingly said it's all cool. My bedroom wall has his posters. I have mouse pads, picture folders, dvd's of his scenes,photos etc and I know I sound crazy, pathetic and sad but I can't help it. He gave me the courage to come out to my family and even though my family knows I love him but they don't know I'm at a point where I feel physically sick when I think of him too much cos i want to be with him so much. The worst thing is that He's straight and I'm gay so it's even MORE impossible but I keep thinking maybe if we met (which we have once and he gave me a kiss on the cheek) he would like me and we'd fall in love ahhhh I know that sounds crazy cos i know that will never happen. I some advice on what I should do. I'm 29, living with my mum and I've never had a boyfriend maybe that's a part of it? It seems to be getting harder and harder each day. half of me wants to get over it and the other half loves how i feel and most of the time i'm only happy when i'm thinking of him.
