I know a little of what you are feeling and I understand. I see you are purchasing a home. I have been in real estate lending for over six years. If you have questions about the process, I would be more than happy to help you understand the process. I can give you an unbiased opinion so that you'll be able to relax when it is finally time to sign the papers.
I understand how it feels! Things can just be so overwhelming. I am 27 years old and all of my friends have kids and are married. I know I still have time, but it seems like I am feeling pressure when I go to a wedding or a christening because everyone asks the same questions:What aren't you married? How come you don't have kids?" When in reality, I am just not ready for children. Not even sure if I could be married. I know you are sick of feeling alone but your time is coming soon.
Buying a house though, is a great thing to do. You are making a wise investment and you will finally have a place that is truly yours. Like everything else in life, when your turn comes, it will happen. Just have faith in YOU because you are the key to your happiness. It is taking me a long time to get the hang of it too. I just need to be nudged along the way, as do you.
