Honestly, who even start with this word that men shouldn't show weakness? We are all humans and we need to behave as humans. Just because you're a guy doesn't mean you can show your weakness or ask for help. People have this mindset that only women can show weakness but what about men that are facing a lot and need people? Truth is, many people are facing a lot but just using smiles to hide their pains and problem. Because some people are laughing doesn't mean everything is good for the them. Some people doesn't have a choice than to hide their pain because there's no one to run to or share their pain.
But I will say you should take it easy and never overthink because thinking too much can cause another thing in the body which is not a good idea. Just look for someone you trust and comfortable with and share your pain because carrying it alone is not a good thing. And always do something that will bring smiles to your face and make you think less.
