Feeling sad and Discouraged ..

I made up my mind today was my last day testing .. it’s so draining and disappointing then everyone around me is announcing their newest additions or adding on to their family and I’m more than excited for them especially my 2 sister in laws but then there’s little ol me after my 3rd born I got pregnant again and ended in a miscarriage , since then it’s been negative after negative… my husband is trying to make things positive instead of me being swallowed by the feeling of disappointment but I can’t help how I feel, I just can’t shake the feeling that there is something I’m doing wrong .. most definitely will be expecting AF in 5-6days . This mama is tiredddddd 😒🥺
