You need to see your prescribing doctor and discuss this with him/her. You don't say why you wanted to stop, only that once you did you felt depressed. That may be a normal reaction to abruptly stopping this medication, which is never a good idea without consulting your doctor. Perhaps this particular patch was too strong for you, you could have had a negative reaction to it, or if it was side effects that made you stop, perhaps those are normal for this medication and in time your body would have adjusted to it. All of those are guesses and opinions.
For the real answer, you need to see your doctor.
I wish you the best
