Welcome to trading. Yes, it's a lonely pursuit. Even when you become accomplished and the money starts rolling in and your friends see you quitting your job and spending it, they still won't believe it.
I've got 3 things for you to consider:
1. Keep in mind that trading is essentially a white-collar job. (How so? You use your mind and a computer, you study, you read, you strategize. You are not fixing roofs or flipping burgers.) The fact is that most such jobs are lonely. In my estimation, they are worse than lonely, because you inevitably find that a small but significant fraction of the people you have to work with every day are crazy. You might spend some time in meetings, but mostly you're at your own box quietly doing your thing. So trading is really not that different from other jobs held by knowledge workers.
2. Find some other people you can rub elbows with who are interested in trading. Join a meetup group (or start one). As you get better at trading and get to know other people who do it, you'll find out that most of them know less about what they are doing than you do. However, it's still fun to talk with people about trading. BTW, they'll be no different from your current friends. You could tell them every single thing that has made you successful. They will listen politely, but they won't believe you and they won't want to try your methods.
3. Your friends, like mine, are infected with it-cannot-be-done-itis. BE THANKFUL that you do not have this disease. For all of us, it's primarily our own minds that hold us back. You won't be able to change that about other people. Most of us traders beat our heads against the wall for a while before becoming successful, and I suspect that most people who try to trade quit during that interval. Congratulations on persisting.
Best wishes with your trading.
