Maybe it’s just me, but has anyone else been feeling like things have been different at work since returning from your maternity leave?

I’ve always loved my job and I had worked there about 2 years by the time I had my daughter. I took 10 weeks off and returned about the middle of May, but I returned at a part time level Monday’s Wednesday’s and fridays. Ever since I’ve returned things have just felt different. Since I’m part time I feel like I’m out of the loop a lot of times and I’m not told things that I should know. Also the person who I thought was supposed to be helping out when I wasn’t in on Tuesday’s and Thursday’s, now isn’t supposed to do stuff for me and so now I have the same amount of work to do but I have to do it in 3 days instead of 5. I also feel like I’ve been treated differently by members of our management team(I’m also a manager) I feel like people have been talking down to me and I just feel like my boss doesn’t like me very much, and hasn’t been happy with my work lately. Idk if it’s just my postpartum hormones or what it is, but I just don’t like my job anymore. If I could quit and be a stay at home mom I would in a heartbeat but that’s just not financially possible right now, but I’ve also worked so hard at this job I don’t want to just give it up.

Anyways im mostly just venting, but also wondering if anyone else is struggling going back to work as well?
