You're going to go through a rollercoaster of emotions and that's perfectly normal. People are going to attempt to drag you out, meet new people, set you up with people, but all the while you're still going to feel some what disconnected from everything inside -- and only you know when the time is right, that you can enjoy life again.
A lot of this is attempting to pick up broken pieces and glue yourself back together, but you can take as much time as you want, you're allowed to wallow, sulk and even be sad, that's just a natural part of life. I know someone who got dumped after 4 years together with someone, and in my head I'm wondering "Is she not interested in me?" even though we've hooked up plenty of times, but the thing is, I don't know exactly what they're going through.
You will have your highs & lows, your lights & darks, but remember you've got so much potential to become something & someone great, when you're ready to begin again, the opportunities will be waiting for you.
