New to breastfeeding and struggling

Mi

My milk came in when baby girls was 4 days old (she is now a week old) and I have been getting painfully engorged😣 Also at each feeding she would get either full and my boobs would still be painful and leaky or would she would choke because there's just too much milk😕 i feel like I'm getting so frustrated with all this! Tonight I pumped for 15 mins to drain my breast and pumped 14oz after nursing her. She woke up for a little snack and I ended up giving her a 2oz bottle now I feel like crap because I really want to just be able to breastfeed and when I go back to work I'll pump and breastfeed... I'm just so overwhelmed and don't know what to do.
