It's worth looking into make support groups. There's various movements starting up support groups for men run by men, who are trying to break that stigma. I don't know where you are based but have a Google and you may find a local one.
While, anything is probably better than nothing, I've found that it's crucial to find a therapist that one 'clicks' with. I wasted quite a bit of time sticking with a therapist who didn't help (and possibly made things worse, much as she meant well).
If a therapist is not an option, I also recommend support groups. In some ways those have been even /more/ of a help than a therapist, because the fact that they're not paid does matter, and the fact that it's a solution without an end-date comforted me.
As a thirty-something, 1) I wish that I looked for help earlier, and 2) I would do everything in my power to move to a different place if I couldn't find the support wherever I was. It's been /that/ helpful.
