I can only imagine how daunting that must feel. You're already on the right track by reaching out here, and by recognising that you're going to be going through extra stress in a time that's already incredibly stressful!
I would suggest reaching out to your friends online/via text or phone if you can? I know I myself have been making an extra effort to play games online with my friends in a group chat, and just messaging people more through facebook and stuff to make sure we're all staying connected and it helps to not feel so lonely.
Also, I'm not sure what your reasons are for breaking up, but perhaps it's a good time to focus on yourself? Find something you've been wanting to do and have a go. Go for walks, read a book, take some photos, whatever makes you happy. Treat yourself, focus on loving yourself and knowing that you're ok on your own.
I hope this helps somewhat :)
