i have tinnitus for almost 10 years now..i hear ringing noise 24/7 since I first got it. my advice is for you is to learn to adapt and accept it...it'll get louder the more attention you give it... it'll not go away completely but it'll become minimal once you don't think about it. Our brain is very good in adapting to this and you can "train" your brain(& yourself) to not think about it. Trust me...it works... and also change your mentality of thinking it as as something annoying, instead think of it as something that's a wee bit inconvenient. That'll help you to start with +ve thinking. suicide is just an easy way to escape things...don't do it.
