Hi
@alex01, I work full time, and also look after my daughter with intrusive, loud, multi-sound, tinnitus.
To begin with, the walls of reality came falling in on me and I couldn't comprehend living with it. It wrecked my life. However, the longer I've had it the more I've adjusted and nowadays it's no longer a major concern of mine. In fact, I have other health problems that I rank above my tinnitus in terms of being a concern to me at this moment in time.
The best advice I can offer you is not to read too many horror stories, and to take comfort in the fact that most people feel better over the passage of time. When we're low, it's easy to assimilate everybody else's problems that we read about, which can compound everything and add more weight to our own situation.
Doing activities that reduce stress will help you a lot. You could also try fasting and then cleaning up your diet as an ongoing thing. Exercise is also really good for fighting stress hormones. Ultimately, you have to immerse yourself in something, whether that be a project or a hobby, you have to occupy your mind to stop you from obsessing and ruminating.
Going to work would be better than sitting at home because you can interact with other people and you can focus on doing something (unless you work in a noisy factory or something). Isolating yourself will make you feel worse and it's likely that this will encourage you to sit online reading about tinnitus (like I did), which will not help you. Doing this will only feed the tinnitus and will keep you in a bubble focussing on it.
It takes time to accept it, so try not to think about your future (again like I did). Until your future rolls around, you have no idea how you'll feel and you cannot trust what your thoughts are telling you when you are under such duress. I've learnt this lesson twice in my lifetime.
Good luck, look after yourself, and don't put a timescale on anything.
