Get. A. Therapist.
More importantly, get a therapist that you get on with. Get a therapist you can laugh and cry with. Get a therapist you can tell tell to fuck off when they tell you things that are hard to hear.
Therapy can positively affect so much of your life and I wish I had done it sooner. I was a pretty successful person before therapy by most measures, but every day I would still do things that would actively make my life worse. I couldn't see it at the time, but I did.
Now, every week I look forward to getting advice from someone who's job it is to help me and give good guidance. His job isn't to be my friend, or to love me, or to make me work. His job is to apply his expertise to encourage me, ask me important questions, and tell me when I'm being an idiot.
I had a good childhood, I don't have much trauma. Yet even so, therapy has made my life much much better. Mine costs £60/session (one per week), and I do it via Zoom. I am absolutely certain it will save me more money than it costs me.
I know the above OP seems to be asking about work. But I think this still applies. A good therapist will help you think through the available choices in your work life too.
And, if you'll forgive me a more emotional plea: If you are a man, this all goes double. The male suicide rate isn't where it is because we're all doing fine. It is where it is because we're not doing well at all but haven't really noticed.
