What should I do?

I have been with insomnia and depresion for the first time in my life since about 3 months ago, and all this time my boyfriend was supportive but we were in a long distance relationship since I am studying abroad and it was very hard to keep up with it. Most times I was so frustrated about my problems that I would just push him away saying mean things and suggesting breaking up. One months ago he said he had enough and we broke up. This month has been horrible for me because I know that I love him but my act and attitude weren’t right. I have tried to talk to him many times and he just doesn’t want to have anything to do with me anymore. I’m going back home in two day and I want to see him but I dont know what to do or what to say.. any help?
