I need some advice on sports and money!? im almost 15 and really stressed. I feel like i cant go on?

I'm an average 15 year old girl I would say.

I'm just feeling like i'm going to become depressed and screw up somehow.
I used to be very good at soccer and played for a good travel team up until my u14 spring season when I got injured. I was out for the season and I came back weak for fall and then my spring season [start of april only] it started to come back to me because I play very well at my hs try-outs. The week after practice had started I got injured once again. From then on i knew my soccer career would be over even though i still love the sport to death but my parents are not doing well at all money wise so i couldn't play this fall and my chances of making varsity are very slim now. On top of how sad that is for me my best friends dad is making tons and tons of money and shes playing soccer and is always talking about it to me even though she knows what situation i'm in and whenever i try to talk about it she doesnt really care. she just wants to go back to school shopping with me since her mom is giving her $300 for and i have to sell stuff on e-bay to get my school money.

My parents have a shop and we have a cottage and last night they told me we may lose both because they can't make the payments. We were fine until the economy got poor. And we may have to sell a car.

It's very very very tough times for me and sometimes i just feel like giving up. I want to grow up and suceed and i know i will if i do whatever it takes (school) but its very hard right now since i have no one who cares how depressed i am about soccer and on top of that my friend to rub in my face about her dad making six digit salary and how her soccer is going. what do i do? I want to feel better and it seems impossible. I need words of wisdom please

My friend went through something a lot like what you are going through. And even though I am her best friend, I had no idea how to help her. Your friend may be the same way, it isn't that she doesn't care it is that she does not know what to say to comfort you. But if she truly is doing it to be mean, than you need to dump her fast. You do not need someone you care about making you feel bad, distance yourself from her and make friends that have either been in a situation like yours or are able to listen and help you.
If you want, explain to your friend that you would like to go school clothes shopping with her, but you simply cannot buy as much as she can. Or just explain why it is hard for you to go with her and leave it at that. If she cannot handle that, that is her problem not yours.
If you have time, during the school year try to get a part-time job so you can afford soccer. If that is not a possibility then try out for a recreational team that usually does not cost as much. If your school offers it you can also try out for girls soccer at your school, which should not cost more than $30 for the season.
But if you are beginning to feel depressed then see a counselor, or somebody that can help you.
You can email me anytime, but really don't know how much help I will be. =)
