Suicidal thoughts isn't serious if you actually stop paying attention to how tough it is and start focusing on the problems.
Had plenty of those back in school when I was a bully victim. It went out of hand when I went to see a counsellor, after some discussion that pinned down the real "problems", it became "homicidal" thoughts. Biology textbooks taught me that kidneys are the collection of major blood vessels other than the heart, so sometimes I see that bully's back turned, I have this urge to just stab him in the kidney and let him bleed to death.
I am glad that I have friends outside of school who are equally outcasted, they are a source of companionship when my dad lost his job after his company got taken over and my mum wasn't specialised to do anything - the two just vented their spleen at me since my grades went from top 10 to subpar due to bullying and having Mussolini's incarnate as my principal (fat, facist and FUBAR).
Having friends do help. Just look for them. They are somewhere out there.
