I am still navigating the breastfeeding journey with my 9 week old! I didnt breastfeed initially due to baby health issues and hospital admissions so started BF properly at around 5/6 weeks.
I definitely recommend breastfeeding feeding support groups. I found mine really helpful and speaking to other mums made me feel less alone.
Also, you should feel really proud of how long you have breastfed for already! I changed my mindset completely by celebrating myself at the end of each day, whether I BF, used expressed breast milk or formula fed my baby.
Also, I sat in a shopping centre, feeding my baby with a bottle and as I was people watching, I realised that I had no idea who had been breastfed or formula fed. I didnt even know how I was fed until I had a baby (my mum gave us all formula from the outset!) It feels like a huge decision now, but ultimately, you need to do what is right for you!
I did do a post a while back about breastfeeding and had some lovely, useful responses. If you search my username, you should be able to find it.
It's really tough but unfortunately it's in a long line of things to feel guilty about as a parent!
Edited to say, feel free to PM me if you need support although I am definitely not an expert!
