You are lucky to still have both your parents, words that were said to me years ago, and which echo still in my head. Don't waste them.
You are still young and it is your life, and you are in control of it, if you choose to be. If you're being honest with your post, then get help to get off the booze. Allowing anything to control you is harmful, unattractive, and stifling. Then get some guidance to help you find your niche in life. This is the key to happiness, finding something you love to do, that you are good at. Do not compare yourself to others, or to what others have or have not. You are unique and original. Friends, possessions, aren't the keys to happiness. Happiness is not brought by having many friends, lots of money, or many possessions, etc, etc. Happiness is brought by knowing yourself, by having goals, by waking up and looking forward to doing something that you love to do, by helping others, by making progress, by growing, sharing and by helping others, human or animal. You have to be whole before you can add anything to someone else's life. So for now forget about meeting new friends, think about finding yourself instead. We are all here for a reason and finding that reason is key, not only for your own happiness but to add to others, to add to society. In the meantime volunteer, in some field you find interesting. Doing for others will help anyone step outside of their own troubles and help you see another side to life. No one can add or detract from your life but you. If you want happiness then find it. You do know where to look, it is you who has the answers, and it is only you who can get the help you need. Take the first step......
