I highly recommend therapy. Generally, men in the US find it difficult to seek out help. Often they think it's a failing and avoid it, especially in the context of relationships. Therapy is something you could almost do for yourself, if you could work out the puzzle. Therapy can do wonders at breaking the initial problem and giving you some things you can work on.
Therapists can also provide useful inputs for career and work optimization. They get treated as mental health problem solvers, but you may get more optimization out of therapy than attending a conference or doing something that's traditional for career development.
Finding the right therapist takes some effort. Don't expect it to help initially. Do some education on the kinds of things they treat and mental health in general. I suffer from anxiety, but I never made that connection before.
