Yeah, you are far FAR from the point where you should be losing hope. People generally agree that Med schools are pretty willing to forgive poor performance early in undergrad as long as you show improvement. At this point it won't be that hard for you to bring your GPA up to an acceptable range, as long as you are able sort out whatever issues with study skills have been weighing you down thus far.
Taking intense courses like orgo over the summer is generally advised against. I took physics 1/2 over the summer and while I did get an A/A+ I definitely could have gained a better understanding of the material in a less rushed setting. You will want a solid knowledge based in orgo for later biochem course(s) and eventually the MCAT. Even if that does mean that you have to push back your MCAT test/med school applications, being slightly delayed and much more well prepared is the better option imo.
