You don't say what you want help for.
But, your name and your story suggests that you want help for your suicidal feelings. Here's a link to a starting point:

I'm glad you posted. And welcome to SR!
You're life has been difficult, but, look at the things you've overcome! My son is a heroin addict, so, I know how difficult it is to quit using, and you've done it twice. Now, the trick is to stay off. Are you going to NA? Are you working a program at all? Any type of program? Do you have any type of sponsor? Someone you can call when you are feeling "squirrelly" as my son says. That's a start, and it doesn't cost any money.
For your depression, though, there are county mental health centers. They run on a sliding scale, based on your income. As a student, you would probably qualify for low to no payment. Contact your area mental health center, or your local representative for the information on where yours is.
And please let us know how you make out. We care...
I look forward to getting to know you as we both grow in our recovery.
Shalom!
