Gosh, that's sure scary. Was it on purpose? How much did you take? If it was on purpose, you really need support. Maybe things are better but if you went there in terms of desire to end your life, knowing that and talking to someone would be SO important. Effects after an overdose can include kidney or liver issues. It's been long enough that all of the acute situations sound to have been avoided but the ones that you don't necessarily see should be looked into. While you are probably okay, no one should hold info like that back from their health care provider. And if it was a suicide attempt, serious or otherwise, you should share that too. Do you have a decent relationship with your mom or dad?
