Quarantine kicking my ass

I have a child with special needs and almost 6 month old baby. The quarantine has knocked her routine which she depends on out the window. So I’m struggling with her and her behavioral challenges really bad. The baby is teething and has an ear infection. We’re on week 4 of no contact with others. My SO still works. I don’t get much help from him at home and if I do it’s because I have to ask and then it’s usually half assed. I’ve never felt so exhausted and defeated ever than I have in these past few weeks. I never have time alone or to myself. I miss my family. I’ve cried 3 times this week from being overwhelmed. Please tell me Im not the only one feeling this way..
