Feeling Overwhelmed

Every time i see posts about people feeling like giving up ttc I always post positive words to keep faith but today I have hit that point. I feel defeated. I have been ttc for 17 months with a miscarriage last August/September (maybe that's stirring up these emotions). I began spotting today, having cramps. I can feel my period coming and I can't hold back these emotions this time. I have a 7 yr old that love her with all my heart. I am a good mom. I just want to have another baby idk why it has to be this hard. how can it be so easy for some people. just felt like venting holding back tears 💔
