WHY DO I HAVE CHEST PAINS HELP?

Since this week I have been trying to eat a lo to gain weight as I’m skinny & I’ve been eating a lot of greasy foods & pizza 4 days,& soda, that’s when the chest pains began. I have bloated tight belly , then throughout the day I’ll randomly feel rumbling n hunger even tho I have been eating all day. Why I’m feeling this? I got cramps last night & day before random pains in left & right side of stomach. Then rn I was standing & felt weak but I don't know if it’s cuz I’ve been working nonstop don’t rest. 🥺any ideas what I might have?
