Anyone else?

Anyone else lost all their friends since having a baby? I’m quite young, only 22 and had my baby 16 months ago. Since getting pregnant my friends have slowly drifted. I only saw them a handful of times whilst pregnant as whenever I wanted to make plans, nobody was interested. Now my friends don’t even bother to message me at all and I haven’t seen any of them since having my baby. My work friends I have are also the same. Whenever I ask them to do anything they either say yes and bail at the last minute, make excuses or just don’t get back in touch with me about it. It’s just so upsetting for me and I just don’t know what to do☹️
