You need to get face to face advice from a trained advisor who can calculate what you would receive in each benefit, something you we cannot do on the forum. There are also implications in regard to Universal Credit replacing ESA(IR) and Income Support and whilst I don't want to open the subject to debate on the forum, the result of tomorrow's election may also impact on your Decision.
Do an internet search for "welfare advice" with your postcode, town or county.
