No - and that is a pretty heavy drinking. The govt recommend 14 units a week, one bottle of wine is about 10 units so you are drinking 50 units a week.
You are an adult, but this isn’t at all healthy particularly if its more than just a week or two, I’m sure you are aware of the health impacts of alcohol.
You are looking to change the way you feel inside putting in something from outside. This never works, be it alcohol, food, drugs - whatever, the relief is only short term and not only are you kicking your problems down the road you are also making them bigger and creating more of them.
As humans we are supposed to feel sadness it is how we process, we allow ourselves to feel these things - its when we try to not feel it and push them away problems start. I would seek out some counseling or therapy, you can afford it considering how much you spend on booze. You need to learn some healthy ways to deal with how you are feeling - ways that are not self destructive - and this can be done and ia often very straightforward.
I gave up booze 3 years ago just because I was bored of it and have never felt better. Growing up in an alcoholic family I saw first hand the crap it causes.
Good luck, there really are alternatives to drinking.
