To say we're screwed is a pretty strong and exaggerated statement. Obviously there is some truth in what you're saying, in the sense that it makes our lives much harder because we have to deal with things that other normal people dont, and we need to learn how to get over things more than others, etc. So, it requires more effort from our part to deal with things, and improve in life, which leads to things like marriage, new home, job, etc. - much more difficult. But, it doesnt mean we're screwed, not at all. Nothing is hopeless. To me, the moment I hear "Screwed" it automatically translates to "hopeless" or "despair", and that is simply not true. There is always hope, even for somebody laying in bed in hospital right now with a broken leg and unable to move. And I truly hate hearing things like "We're screwed", as that is negative thinking. Think positive, and that will improve your mood and the way you deal with things, and improve your life.
