One reason is because it really only takes one time to use something to get you addicted
2nd reason is that you could use the heroin incorrectly and possibly give yourself a deadly amount and easily overdose on it
I believe you should take a year off and do every prereq you can get at a local college or university. a way to check that would be to go on a computer and pull up the local college, and the college you set your mind to long term. so for instance LTC (long term college) may have a prereq Bio 213 and maybe you LC (local college) has a Bio 217. you would call the LTC and say hey, does your Bio 213 line up with LC Bio 217. Most of the time they will say yes. It saves a LOT of money.
Crepitus is a clinical sign in medicine that is characterized by a peculiar crackling, crinkly, or grating feeling or sound under the skin, around the lungs, or in the joints. Crepitus in a joint can indicate cartilage wear in the joint space.
I've had a friend similar to yours, yeah you can encourage them to eat but don't make them feel to bad about it. Just try to be there for them because there might be a reason behind why she isn't eating, you should maybe ask her about it. If it gets really serious you should go to an adult.
I hope everything gets better : )
