When I was 35, I had accepted I would never marry, have kids or even live on my own. 13 years later, I have been married for almost 12 years, have a 9 year-old daughter and have been a home owner for 5 years.
There are a ton of people who are living the same life you are and those of us that have been there before. As hard as it is, keep the faith - life often changes when you least expect it.
