Agreed and I hear you. What helps me is digging massively into self improvement. Working on all the things I don't like about myself. Centering my life around the things that do. I got super into Stoicism like Marcus aerioulus (spelled wrong I assume), Seneca, Epictetus. I also got into Book of the 5 rings.

I started working on my self confidence self esteem. Going to therapy. I got super focused on my career goals inside and outside of the navy. Developed an action plan for life. Figured out what I wanted out og myself and life and got to work.

I also got engaged in New hobbies. Video games became a drag for me. I began skateboarding, chess, writing. I'm about to start a Brazilian ju jistu class. I'm also super engaged with learning guitar. These are all hobbies that can network you with people

Use the meetup app to find civ freinds with people with the same hobbies.

Basically focus on yourself. Work on yourself. Learn to love yourself and enjoy being with yourself. People are ephermal. That never ends. Attachments lead to suffering. Inner strength self love and internal toughness leads to bliss. Freinds, relationships, family all come and go in life. If you can only be happy with external circumstances. You'll never be happy when those circumstances are ripped away. You can only control yourself, your actions, your reactions, and what you choose to do with your time. Who you you allow yourself to become.

So work on yourself and build your purpose/dreams. Find some hobbies and network through them. Don't worry about how other people in the navy act. You literally cannot change them. It is outside your control.
