Anyone else?

Is anyone else finding it extremely hard to breastfeed a nearly 2 year old ? It makes me so down and I physically feel like crying and running away from everything . I feel like when I have another baby my MIL is going to have the audacity to ask why I’m not breastfeeding this time and I’m going to get really angry and answer in a way that’ll put her in her place but I don’t want to cause drama in the family . What’s a polite but “ don’t get personal with me” response ?
