I don't know what to do

It does seem like you do have a problem with alcohol and the good thing here is that you are making efforts to identify that. You say you can go for months without drinking but you crave it all the time. This does seem like a constant battle.
Your friends mean well by taking the alcohol away from you in order to stop you from drinking more. Though that can be 'frowned upon' in a pub environment. Sometimes having people take the alcohol away from you or tell you to stop will encourage you to rebel. In all fairness. You are the only one who can really make that decision.
You could look deeper into the reasons for your upsets and negative emotions. This does appear to be your trigger point. Going to Alcoholics Anonymous or something similar will be a good opportunity to discuss this. Your 'story' is just as important as everyone else's 'story' or life situation.
Many of your friends may not think you have a drink problem because they are likely to be drinkers themselves. Some may even focus their attention on you to avoid facing their own issues with alcohol. This is definitely the case as you are all at college. There is pressure to 'keep up with the crowd'.
Does your college have a counsellor you could talk to or perhaps a friend who you trust who is not in your 'drinking circle'? Maybe one of your lecturers may help.

Search for help. Sometimes we just don't know what is happening to us and it is extremely important to figure out our real status. Alcohol is there like fake friend making us feel cool and strong for 5 minutes while our real life is falling apart. Everything is under control I was repeating to me for 31 years, but it wasn't. I was 9 years old addict. I was only a Child and alcohol was my escape from home problems. Take care.

Thanks for your post, you're badass brave to admit to having some problems. (We all do, but too few people talk it out.) You're strong enough to share your thoughts with us, and I think you're also strong enough to fight your issues. I'm ACA and I've experienced what it is like to live in a family ruled by alcohol. I don't wish this to anyone. But more importantly, I've seen how addiction devastates people as it progressed, not only family members/friends, but addicts as well. It must feel hopeless and lonely.

"but it only gets bad if I'm upset or feeling any kind of negative emotion. " -> whenever the use of a substance is connected to emotions, it's worth thinking of contacting a professional. It's great that you realise your behavioural patterns, though.

"I feel like I'm not "bad enough" or have a good enough story to go to something like AA, but I don't want to get to that point." - As previous members have stated, THERE IS NO SUCH THING AS "NOT ENOUGH" PROBLEM. Please remember that. There really isn't such thing as to little/alright intensity of the issue to seek help. If you feel you need, help, please reach out to a professional and a trusted person. Everybody deserves help when they need it. It's called self-care.

College time can be tricky and tough, with peer pressure and casual drinking around. Don't feel embarrassed for reaching out. It's good you have this self-care instinct. I wish my alcoholic parent had one, but they never did, and it devastated my family.

Keep on reaching out, bearing in mind finding a professional (some addiction treatment centres and even your GP or any other doctor should be able to help you) and keep on hanging around on 7cups.

Thank you for posting.

All the best
