Need to vent.

I dont expect a pity party or anything I just need to get things off my chest. My baby is 6 months old and I've found parts of motherhood hard and others have been the best thing in the world. She's a great kid and I love her to death. We're having sleeping problems at the moment along with teething and trying to wean. It's been hard, but its whatever. My family have had a tough time as my Dad nearly died on two occasions since a heart attack he had in January, basically surgery went wrong, he recovered and then had complications after that and nearly died again. Then my uncle died. I found that all really hard to deal with as I'm the oldest daughter in the family so I was the one holding things together for everyone whilst looking after my baby. Anywho. My husband is supportive but works alot to support us which is absolutely fine, we need to pay rent you know? But I feel like a burden if I've had a bad day I don't want to moan about it because his sister had twins just before we had a baby and was left a single mum due to domestic violence. So I feel like how can I complain? She's incredible and I've never heard her complain so what have I got to moan about? I feel like the pressure is just too much. Weaning is so hard, I see baby's on insta holding pieces of steak and my kid hasn't really taken to anything really, she's wearing more than she's eating. My maternity ends in September which seems forever away but I'm scared about going back to work as its an icu and I don't wanna bring covid or any other illness home to my baby so I will end up looking for a new job. Again, in the UK we're very lucky with maternity leave unlike other countries so how can I complain? I'm also worried about the child care costs. I don't even know what I'm moaning for at this point, I'm not even sad I'm just kinda numb today. I'm on anti depressants, have been for years before having a baby and speak to my Dr regularly so I'm fine, I just needed to get my feelings out. I'm aware I have a privileged life I think that's why I feel so guilty.
