Should I start fixing my relationships?

If it's broken and you love him/her then I would advise you to fix it.

If it’s a worthwhile relationship

Are they able to be repaired?

Only the ones worth fixing

You should!

If these are relationships you want, and they are fixable, yes. If not, then it's best for everyone to move on.

You will fix them when and if it is important to you. Doesn't matter what we say.

Sure but being vitriolic and sarcastic won't get you far

you could.. or you could get drunk instead.

Only if they're broken.

Best of luck with that.
