I can see how that would be upsetting, I'd probably find that depressing too - especially if I was to compare myself with other people my age and see what they have.
I watched a TV show the other night - it was one of those shows that are very popular at the moment about people who buy houses and fix them up a bit and then resell them for a great profit - it actually made me quite depressed for a day or two because I know I will never own one house, let alone be able to do them up like these people. But then I thought to myself that I have to be realistic and realise that given my limitations, I'm actually not doing all that bad after all - and I really don't need a fancy house.
I have always thought what a nice young guy you are - and you're obviously very smart. One day I'm sure you'll meet someone nice and be able to get a bit of that life the others are living too - I'm sure of it. Take care mate.
