i feel like i need a change in my life, or i feel hopeless?

Make the change buddy - That puts you at the top of your hopelessness - After investing sometime on the fun-side you like, things change(don't let it to override your primary objectives(college) though - be accountable to that too), Situations you were might get past & It might turn out to be less important.

One thing i understood is this buddy -
Life goes on - whether you want or not - but its with you, on how it should be for you :D.

PRAY... I know it sounds like I'm preaching but its the truth! Prayer helps!

Look into yourself and you can see a source of light that grows and shines.
It is a source of positive energy that will guide you.
Think of things that you long hope for, say seeing your family, your friends...etc.
The most important habitat of hope is where it resides within you.
Find "the tunnel of light" and follow it, let it guide you.
watch star wars: a new hope. it is a good movie that brings hope.
also watch the iron man series episode 1-3. they are awesome.
also listen to the dark knight rises music on youtube. you'll feel better.
Ask yourself what is it you want from this life. If you want to be successful, go for it.
play star wars the old republic, and play as a bounty hunter. this will give you a mission and hope in life. (although the bounty hunter phase is of the empire, you can still make light side choices along the way). (similarly, you can play as a jedi knight)

I feel your pain. But you should try to find something you'd like to do. I am 24, and in school and I guess depressed as well, so I started running a few months ago, I feel great after I run and I run every day. Maybe you should try running as well, start slowly, and then speed up and try to cover more milage. After you run, you actually forget all the stress and trouble, you feel accomplished and think more clearly.
Did you already make up your mind of what you want to major in? Are you really passionate about it? Get more involved in it, find people who are passionate about it too. This will make it easier

Change your life by ACTUALLY GOING OUT TO DO SOMETHING. You wasted about 12 years of years life to school about useless things. Do something real.

Volunteer with people less fortunate than you. I wish you well.
