Starting from now

Trying to stop drinking , I drink because I am shy and and the only way I could not be shy and confident was when I drink I could actually communicate in a large group with out my anxiety kicking in . But now every time I drink and then I wake up in the morning I feel like I am always doing something wrong or am I making someone upset or does everyone hate me when I’m drunk and it will just play over in my head and I feel like I’ve done something wrong when I haven’t . But I can’t stop drinking , I’ll say I’m just going to have a few but then that few turns into me doing all nighters and still drinking making everyone do shots after shots with me then I’ll wake up then do the same . Just want to stop myself from drinking so I don’t feel like this anymore . Then I saw this and was like I’ll give it ago hoping it will help me
