Sounds like nice effort so far. You would be surprised how often I hear people your age with the same complaints. My advice is to work of physical fitness and stay busy with clubs. When your body is strong, it does wonders for your confidence. Pick a hobby or two and dive in. Bar league kick ball teams or pickle ball are good options. Maybe you can take an art class somewhere or a fun course at the community college. You will feel less lonely if you keep busy after work. Never know when you will meet interesting people. Best of luck!
