There is much to look forward to, and don't make your job your identity. Do you have any hobbies? I met many of my friends playing pool and darts after work. I met my best friend working. We still get together a couple times a month, and it has been 25+ years. Don't be in a rush to make friends, just open yourself to experiences with other people. The friendships will come on their own.
For 17 years I have been getting up at 5:30 every morning so I can get my family moving and out the door on time. My work day doesn't start until 9:00 after my hour commute. Most days I don't get home until after 7:00. Then after dinner and homework, working on the house, I still manage to find time for hobbies. Unless you work until 10:00PM you should have plenty of time for hobbies, socializing and getting a full night sleep.
From my experience, leave the house. Don't get sucked into television and surfing the web. When you go out, keep your phone in your pocket. Be interested in what is going on around you, don't look bored or annoyed to be there. If you do that enough, someone will eventually start a conversation while standing in line, or whatever. When they do, find a way to ask open ended questions, let them talk. People like to talk about themselves. Listen to them, ask follow up questions about what they talk about.
I'll get off my soap box now. I doubt you wanted my brain dump, but I hope it helps.
