Welcome!!!I remember being 19 and all i wanted to do was socialize, you're probably better off with a few friends as i spent my time in the pub drinking in college, stupid idea, by my 3rd year i cracked down,on the books i mean. if you do better in school if thats what you're going to do, or work, its better if you get a good nights sleep every night and don't follow in my footsteps. if you feel lonely with your friends now, don't worry, you can always meet others, join a group of people with like interests if possible, schedule your time for as long as you can take with people.i remember in grammer school i felt lonely even when i was with a group of people or just even one person. it must just be our pshysical makeup?good luck!!
