Well my advice is this. Make a list of goals, both fun and not so fun, break them down into smaller steps and try to accomplish a few of them.
Tell yourself, it's okay to feel bad, you don't have to feel happy, but you know that when you're feeling better down the road, you'll be thankful that you accomplished these things. For example, the last few years were the worst of my life and yet I look back and realize wow, but I traveled here and I took this class, I saw my first meteor shower I...I did this for the first time, I tried that... etc. etc. etc.
Force yourself to try something new hopefully involving other people.
and then take it day by day. You'll get there. You've already gotten through the worst, the only way to go from here is up!
