Hugs. This must be such a hard decision. Firstly I am pro breast feeding but if you've done all that you can then maybe a calculated switch to formula would be the best. A big congrates to you for persisting this far.

My SIL struggled with my niece for months until the pead put her on a formula that required a script. I am sure it was Pepti???? After a a week or so she was a different baby. Additionally my SIL takes my niece to a chiropractor that specialises in allergies and this has helped tremendously apparently.
