First of all, sorry for my bad English...

As a 29 years old man single for 6 years, with no friend, I feel like I don't want to live this life 50 more years. 

My only social interactions are at work with my colleagues, or when I visit my family.

As an introvert, I don't really like going out, I prefer playing video games or watching movies/series at home.

I thought that depressed feeling would vanish with me making projects, such as buying my own house, but it didn't.

I tried online dating but being ugly and shy doesn't help. My photos are old, since I don't like photos.
And I have serious difficulties in approaching or talking to women. I'm not interesting enough, and I'm always overthinking. And I hate failures so being rejected, which happens often while dating, would destroy my confidence, already low.

I know that my current state won't allow me to meet someone, nobody wants to meet someone who doesn't feel good.

I tried to talk about it with my mom, but her lack of mother figure doesn't help me, she unwillingly has hurtful words trying to reassure me. Plus, every time I visit my grandparents, they keep putting pressure on me to find a women, and give them a grand child, because I'm the only man in the family who can perpetuate my last name...

My professional life is a success but not my personal life. For years, I kept repeating myself that I would have failed my life if I didn't have a family at 30, thus life wouldn't be worth living and I should kill myself at 30. 

So here we are, I'm 30 next year and wonder why I should live this life without love.

Thank you if you read this, and thank you for your advices!
