Excellent idea, but don't forget to blame European Union and Mexico!   

Ending a relationship through text is kinda sad. It is avoiding confrontation aka not being a social person and hiding your true feelings.

She has been very kind to you, but that doesn't mean she can expect every guy to stay with her forever because she offered help. Life always changes and so does your view on things. You need to clarify to her that you have other goals in mind right now and she is not to blame for that. Be completely honest and tell you will always love her and she has a place in your heart. You can even stay in touch and help eachother our as friends if you feel like it to show your appreciation.

only if they deserve it.

its kinda of a cop out. lazy way of going about it, but some are not worth even that. just depends on the circumstance.

also, it could back fire and they get obsessed with you then its a whole another can of issues.

That's a pathetic way to break up with someone. She doesn't deserve that. Do it on person or at least through the phone.

Have you talk to her about any problems you two might have? If you really love her, talk to her first and try to work things out.

Yes do it that way. In a year she won't even remember as she will be tapping some other guy.

No offense, but it sounds like you're the problem in the relationship. She's dealt with your problem with drugs, depression, you not wanting to do things, and you not caring about your health. She's even decided to attend the same school as you, because people know one of the biggest things to end a relationship is distance. She's a committed chick. And then there's the situation of asking if you should break up with someone over a text, especially despite all she's dealt with, when that's pretty common knowledge you shouldn't do that. Heck, the only reason you are asking about it on a forum, is because deep down you know it's shitty.

You know what, yeah, end it through a text, email, sign language. End it through morse code if you have to. The young heartbreak she'll experience in the near future is nothing compared to the turmoil she'll put her life through and the opportunities she'll have lost by staying with someone as self absorbed and callous as you.

Honestly, as with a lot of threads like this, if you have to make a thread to ask about it then it's likely that deep down a part of you already knows the answer.

It'd hurt more if it was done through text. And it'd make you look like a huge dick. 

Telling her that "you'll always love her" is like giving her false hope for getting back together. Plus, that line is so cliché and cheesy. 

Sounds like you are doing her a favor, so go ahead.
