the same meaning?

[Anonymous]

Are these all OK and do they have the same meaning?
- I've never dated a girl. / Really? [________]
1. You're pathetic.
2. That's pathetic.
3. You have my sympathy.
4. I'm sorry for you.
5. I'm sorry about you.
Thanks.

(1 and 2. have the same meaning).

3. You have my sympathy.
4. I'm sorry for you.
(3 and 4 have the same meaning).

5. I'm sorry about you. (Unnatural).
