Just let him know that you still have feelings for him but that you'll wait and give him time to sort out his depression and get back on track and stay friends, then you might be able to get back together. That's the best thing you can do right now, just give it time for the depression to become manageable for him and for you both to work out what you want. Don't stress over it just stay friends, let him know how you feel and support him if he wants help with his depression.
