Agg. systemic mastocytosis. this mean my anaphylaxis food/drug allergies will now end since on cromolyn? could itp dx be part of asm or can have both?

No, and No: cromolyn will not end probability of anaphylaxis, and if it happens needs to be treated, ITP isn't part of the disease, yes a patient can have both as separate diseases, aggressive severe mastocytosis is a rare disease, much rare than systemic mastocytosis, which is already a rare disease, diagnosis / management need to be in a tertiary care facility, need to adhere to treatment well & follow up
