Sorry you've had so much family pressure about marriage, etc. I know it's really easy for me to say this (or should I say, sit here and type this), but if you can, please just ignore that stuff. It's natural to want to meet someone and to get married, but let me tell you, marriage is not always the key to happiness. It's definitely better to be happy alone than to rush into a relationship/marriage with a person you won't truly be happy with.
Urgh -- I sound like I am spouting cliches, so I'll shut up now!
I can definitely understand the whole wishing you had a different childhood thing. I wish that myself a
lot. I grew up with alcoholic parents, and even now that I'm in my 40s I still get knots in my stomach when I have to talk on the phone to my father.
I hope your uncle manages to stick to a date to help you move, soon, so you can get out of that stressful environment!
