Unfit for my age?

Hello People.

I've been away from here due personal issues.

Got 40 on may.

I feel like for mots things i am unfit for my age since i never had a relationship and most of my life i was looking for someone who could care of me because i had a big hole emotionally speaking which is a major lack of affection.

I feel that my time is up and i don't have a right to find someone and i have to deal with loneliness for whatever is left of my life.

The question is, since for my lack of affection for all my life i was deprived of most experiences normal people do, it is normal feeling unfit for things that should be done at this age?

For example i feel i am unfit to have a family of my own since i never had a girlfriend when i was young, there fore never had the experience of deal with a relationship. If i have a relationship i could notice my inexperience and that might spook away my potential couple.
