Forgot to take my anti depressant

Nope, You can just take it in the morning. You aren't the first person to forget nor will be the last, I've done it a few times.

Normally when you miss a dose you take it as soon as you remember unless it is close to your next dose time, then you'd just take it then. Did you take it now? It's still okay to take it in the morning, that is long enough time between doses.
