what is wrong with my baby?!?!

For the past 24 hours my 2 month old baby boy has been extremely fussy to the point where my frustration was maxed. He has been staying awake more during the day, eating constantly, crying a lot, wanting to be constantly held, sucking on his hands, and feeling warm but no fever. I have been under a lot of stress so maybe this is his reaction? In one day I almost got a divorce, realized I have to put my grandmother who is living with me in a home because she is too much care, and I had to give away my cat for scratches hint the baby last week. The weather is changing and maybe he is sensitive to it?
