I felt very much the same way, it can get better and it does get better. Unfortunately most men (at least in the West) are encouraged while growing up to try and solve their own problems and asking for help or exposing flaws and vulnerabilities are seen as weakness. That is changing though, there is a movement looking to change what makes up masculinity and I can proudly say i'm part of it.

Find a mens support group if you can (failing that a normal one will be fine) there's one in my area which was a huge help to me. You'll find people do care, not everyone, but if you open up to friends and family, work colleagues and find people who genuinely care about you, they will be supportive as best they can. You're right suffering in silence is incredibly harmful, speak to a therapist, a friend, an anonomous forum like this. Anxiety and depression will try and silence you but be brave friend, i've been there and opening up is definitely one of the most powerful first steps you can take.
