Close to a mental breakdown

I will mention that I have mental health issues and I admit that this is affecting things also. Anyways my college is doing a senior capstone project that every student who is graduating has to do. It is a group project and mine was a research type project. At first I threw myself in headfirst and working in a group project. I have never done a group project (or anything for that matter in my college) since it is an online college. So, this is my first time both the senior capstone and group project. I was the group leader as I was the first to set up the project and because I gave myself the job as I was so excited for it when I first found out about it. The project is 3/4 of the way finished and everyone in the group has stopped doing anything for it. Nor including myself. I am the only one who is continuing to work on it because it is my diploma and my future career. I am so tired of trying to get people to do stuff. I have run through all of my ideas on how to get them to do stuff and none of it worked. I am so close to dropping this class and then dropping out of college. I have asked the teacher for help and they just say "Oh well, this is a group project you guys will have to figure it out"<br><br>I don't know what to do and I am so tired of hearing all these horror stories about group projects and it turns out mine is no different.<br><br>My mental health is in shambles and I don't know how much more I can take of this. I am so close to hitting rock bottom and I don't know how to stop it.
