What do I do?!?! Please HELP ME :(?

This is kinda long but if you read it and help me out I would really APPRECIATE it. Not many people help each other out in this world anymore....I don't really know how to say how I feel. So I'll try my best. First of all I'll like to say I'm a type of person who absolutely loves to train. I love keeping track of all my runs and the running itself. I've put in a lot of hard work in but I don't know why every time I race competitively I am so hard on myself. My high school has a lot of track races and I'm counted on heavily for points but I get no credit from my coach at all. For an example I was the second highest scorer ALL season by a couple points. The girl who got MVP only got it because she was a pull vaulter and did hurdle events instead of relays which the points split. The events I do are the 2 mile, mile, 800 and 3200 relay. Those are the LONGEST, TOUGHEST events in track. But when we got awards I was not acknowledged at all. Girls on my team who barely even come to practice or put in miles got awards. I feel like all season I was treated like crap by my coach because he doesn't care about the distance runners at all. He cared about the sprinters. Well anyways at the state meet It was over 100 degrees in the stadium but mostly I just gave up mentally and couldn't force myself to care anymore. That was a week ago and I'm still really mad about the whole track season. I really think I could of done better and had better times and fun if I just trained on my own. I really am a nice person. I don't complain much unless something unfair really bothers me. Now I'm confused and sad. Because I had a dream to run on a team in college because I thought it would be fun. But now I have doubts. Is running even more competitive in college. Will I get any credit. How can I care more? I know these are confusing questions that may be vague but if your a runner or person who went through a similar situation PLEASE help me out with some advice!!
