I even don't know how to begin but this shit is killing me inside every day , and it's a thought like the other thoughts i have been suffered,

Before starting this let me tell you that I'm 26M , to myself and friends i appear handsome cause of my height and hair and body shape etc ...

I don't know what is responsible for this but i've been thinking a  lot that i'm not enough for girls , that i cant appear to be hot for them anymore , i have been thinking like this for a long time now that its not a thought anymore , i actually see this in their eyes , in their manners and morals with me,

for example;
i was out with one of my friends last night and i couldn't stop myself from thinking , i thought about everything that came to my mind , and then we asked out two girls and here we go my overthinking started again , 
i constantly was overthinking again , do they like me? 
am i even likable?
how is my literally non handsome friend ( no offense though) can flirt with them easily and i'm here sittinh constantly thinking about my inabilities,? 

Guys it has been so severe that this shit has covered all my life and i can't even breath like this , 
I want my old self back , i wasnt like this .

Another thing is , nowadays i constantly fear the thing that i somehow wont be able to fuck a girls because of erectile dysfunction,
it has happened to me before and i fear it will happen again to the extent that when i'm out with a girl i literally am sure that i wont be able to penetrate this girls back at my place and therfore my fears start to show up and here we go..

last night we smoked weed too , i smoked weed after two years and it was the same , my overthinking overheated and i was this little ball of awkward shit sitting in thr car saying nothing and all the bad feelings doubled and i felt like shit even more .

can someone please help me out here?
