Turned 29 y/o few days ago and I've started feeling that maybe the way I live is a lie?

I was pretty secure in my life's decision - being child-free, find boyfriend who will travel the world with me, build career in IT and overall live my life to the fullest. I have no friends, I spend most of my free time in front of computer and my flatmate is my mom and till now I was pretty happy or at least I thought so.

Everything has begun when my brother got married this May and the whole day I kept thinking how endearing it is to see that so many people genuinely care about him and I felt quite envious. Also my cousin gave birth to her first child and when I went to visit them, I've started thinking that it would be nice having someone coming home to that isn't my mom (lol) and a little family.

I was disappointed and abandoned by "friends" so many times in my life that I'm now unable to form any deeper bond with people and I treat them like they're disposable (I'm nice and friendly, e. g I enjoy being around my coworkers and I occasionally bake for them but If they were to leave, I wouldn't care) and I feel like I repeated to myself that I prefer to be on my own and that I hate the world so many times that it became my "truth" when deep inside I am lonely and crave to be loved.

So for 18 years I thought I knew what I want from life but now I feel like I don't know myself anymore. I don't know whether I've just been influenced and in few weeks I'll be back in my "I want to be left alone" era or If this is something that needs to be discussed with therapist maybe (?)
