I feel similar to you. I'm a 20 year old university student as well. I want to get my degree but I doubt I'll be putting it to good use. Lately it seems like more days I cry out of loneliness/frustration/inferiority than not. Being happy seems so hard some times. I'm trying to be grateful for all the things and opportunities I have but it's hard not to look at the negative side of things. If you ever want to vent or share experiences feel free to pm me.
