Please help me decide how to taper off of escitalopram again, as it hasn't helped my severe OCD intrusive thoughts.

I have been on it approx 9 weeks. Doc told me to taper off if it over a 1 week period to go on sertraline, but I don't think I want to be on another SSRI. So, am wanting to taper off of it altogether.

I was on 10 mg for 5 weeks and went up to 20 mg for about 3 and a half weeks.

I then cut to 15 mg for a couple of days and 3 days ago I dropped down to 10 mg.

I want off without horrible withdrawals. I am trying to accept that what I have is truly ocd and stop avoidance to get better.

Please advise how to get off escitalopram quickly without experiencing withdrawals.
