I think my journey is being cut short

I could really use some advice or words of encouragement more then ever. My baby is 9 months and we’ve been told for a second time to start supplementing. At 6 months I didn’t supplement only because I wanted to get his weight up on my own. A month later his weight looked good and I thought we were in the clear but now at his 9 month appointment, he had only gained .4 oz in a month and his doctor wasn’t happy. I’m not concerned about his weight only because both me and his dad were small babies and he’s teaching all of his milestones and he’s happy but I am getting really annoyed with everyone commenting on him being skinny. It makes me feel like people think I’m starving him when he’s definitely getting fed. I’m almost sure he has ties and that’s probably the issue but I don’t have money to get them revised so I believe our journey is coming to an end.

I almost want to quit just so I’m not concerned about how much I make or pumping or if he’s eating enough or if I can take this or do that while breastfeeding. But at the same time I love this journey and the bond I’ve created with my little boy. A big part too is now he has gotten to a point where he won’t take bottles anymore and only wants me so he can eat. And I know supplementing doesn’t mean the end but in my head it’s almost like they’re telling me to quit because how am I not good enough on my own. And what’s the point of continuing if he’s just going to be getting formula anyway. Isn’t the point of breastfeeding to kind of stay away from formula? And the less I tell my body to make the less milk I make which I’m turn just ruins my supply and I’ll have to quit anyway right? I’ve almost come to terms with just quitting. My goal was a year but I should be happy with how far I did get right? We had a really rough start where he had formula for the first week or life and I didn’t even think I’d make it this far so I am blessed but it just hurts that I’m not enough.

Thanks in advance💕. This mama is a mess today😂
