You should try to do it yourself first, and then we can help you if you don't get it 100% right.

As Michael says, you should try to do this yourself. Here's a hint, though: If you're trying to put 'got up' into the passive voice you'll get nowhere. This is an intransitive phrasal verb, and it has no passive form. All you need to do is put 'someone interrupted me' into the passive. This is very straightforward past simple passive, so it shouldn't be a problem. Leave the rest of the sentence as it is.
