Possible aspgers how to explain to doctor

Right I fell I may have aspgers but I dont know how to explain to the gp

The reason I fell I.may have this is after reviewing my life and looking into my self more deeper

1) I have selective eating disorder any other foods I cant touch as it makes me sick

2) I get really nervous around people and even people I know and can shut down

3) I can sometimes go into a deep throught and forget about it and end up somewhere else if im on a train orbus

4) I dont like people hugging or kissing or close contact

5) I can get fixed into things for hours and find things interesting such as trains cars etc

6) I cant remeber peoples brithdays but I can remeber number plates of old family cars from years ago many cars now scrapped

7) I cant sleep well most nights and struggle to get up in yhe morning 

8) loud noices can scare me a lot and when people argue I can.go into meltdown

9) I cant take drinks from people as it makes me nervoys ive got to.make my own drink

10) my mood goes up and down

11) is the most embrassing if someone pisses me off ir change my day I end up sort of talking to.myself loud like saying things like. They always runing my day. I cant be left alone. They always want something. Its not a convo.like hello. You good then im good its more like.muttering stuff loud where I say they always runing my day I cant be left alone. They always want something f###ing idiot 

I been told I have had Selective eating disorder depression anxiety. But looking at my life im thinking theses all could be related to aspgers
