Is it normal that i think my knee injury ruined my life?

Okay so maybe saying it ruined my life might be a bit dramatic..But really I blame it for my lack of confidence and happiness. My junior year in high school I had this knee injury right at the beginning of my soccer season. What really sucked was I didn't even want to play soccer that year, but I let my friends talk me into it. And that year was when I really became passionate about running. Plus my confidence was at an all time high. I had friends and went out and was happy. Seriously running was everything to me. It was the one time I felt in control of myself. Because I was so good at it I felt like I could go as long as I wanted. Almost like I felt unstoppable and invincible. Right after the injury I went to see a doctor and was told I had to have surgery on my knee. I couldn't stop crying because I knew my leg wasn't gonna be the same anymore. I wasn't going to feel invincible anymore. I'm a sophomore in college now and I can't stand to run anymore. The pain just reminds me how I now have to live by limitations. I no longer feel in control of myself. I feel like no matter what I do, there's always a limit. People say you can do anything. No, no I can't. I seriously haven't been the same since then. I give up on everything. My selfesteem is lower than ever. I don't have any friends and I rarely go out. If I do, it's just for a drive away from all the crap at home. I know there are people who have lost worse things--like an entire leg, arm, and even loved one--and have pulled through. I envy them so much. I don't understand how they did it. Running was seriously the only way I could feel happiness and pride. Now it's gone. I keep trying to find new ways to feel the way I felt when I would run, but nothing comes even close. I hate it. I know I sound like a stupid girl in her own pitty-party, but I seriously can't seem to pull myself out of it. I wanted to see a therapist, but I know he/she is just gonna say try to find something new. I've been trying and nothing is helping.. Is it normal that I let this one injury ruin my life??
