It seems I have gotten minor alcohol withdrawals

What does one do in this situation, I just turned 18 I didn’t realize but I’ve been drinking for maybe a week or 10 days since my birthday very heavily so ik I’m off on the days because looking at post and picture history it’s been longer than j originally thought I’ve finished over 2 bottles I’m not typically a drinker and have had some benders before in the past which can make one more susceptible to withdrawls, I know it’s not bad but it’s overlapping with bipolar symptoms and making live very difficult, I haven’t had severe symptoms ik I’m only on the 2nd day but already my heart is beating harder I’ve just started to have the chills creep up on me today and yawning and I haven’t had shakiness which I feel is a good sign I have been a lot more agitated and on edge, I wouldn’t say but I’m definitely getting a bit of heart pain, bipolar symptoms are messing with the agitation piece which has made it harder to control temper, not in an abusive way but I feel like I’ve gotten into more arguments specifically today but also have fueled them and have been talking extremely fast and it’s been very hard for me to sleep and I’ve already had insane dreams from hormonal changes but they’re getting much worse, I’m very tired but am unable to sleep again I think this is very minor but I have heart issues already so minor it’s hard to detect but does effect me, I sled someone to check my heart because it’s usually been working hard and they were saying it’s definitely really hard and again I’ve been having heart pain more specifically with the agitation and pressure talking, I’m unsure of what to do right now, I’m out ofc which is a good thing, not fully but I wouldn’t want it to get worse, I’m thinking of taking melatonin to help although I know it won’t do as much because this is completely different, I’ve had opioid withdrawls and they’re agonizing and feel worse than this ik not as physically dangerous but I don’t exactly feel amazing either and have way more agitation right now, I was in a mixed episode before I started heavily drinking like deep in one so part of it is related most likely
