Breaking point 😩😖

Ftm to a 3 month old. Today I reached a breaking point. Baby been wanting to be held almost all day. If I put him down he'd either be fine for a few mins and then cry or cry right away and now it's bedtime and I just lost it. Started bawling while feeding him to put him to sleep and I'm just sooooo sooo tired. All I want is to give him to someone so I can sleep. This whole week I've been feeling sleepier than usual. I was feeling it a lot right now so I put him in his swing and laid down on the couch but it seems as soon as I drifted off he started crying again so I brought him upstairs and changed his diapers and clothes while he cried and and then starting nursing him and I started crying.  When I'm at my lowest I have thoughts like there's nothing great about being a mom and I hate it and why the hell did I become one??! I'm so exhausted. I'm a sahm too! How do you working moms do it?!??? 😩😩I'm losing my sanity bit by bit. The longest he sleeps at night is 2-3 hours. The waking up so often is driving me nuts. Plz God make him sleep longer now. I really really really really need it
