Thanks so much for being there for me, guys. Just your responses have meant a huge lot to me.
My niece, who is also bipolar and battles with SI, came around today to help me through it. We had a braai (barbecue) and I took a Seroquel 25mg tablet which knocked my flying. I was so drunk from that tablet that I slept the entire afternoon from 1 till 7pm. Feeling a lot calmer now. Not having noise in the house helps because noise winds me up really quickly when I'm manic.

Thanks again everyone for all your help. Hugely appreciated. Peter
