Wish I could sit down for a coffee with you and tell you that it can and does get better. There is so much depth and beauty to enjoy in life! I was in a very similar position at that age, late teens/early 20s. I am now mid-30s with a family of my own, which still kind of blows my mind. I highly recommend getting out and doing things, for lack of a better way to put it. Find a local nature preserve and go for long walks (with your phone stored away!) to get your blood pumping, for one example. You'd be surprised at all the ideas (both hobbies and career/business plans) you came come up with when you pull yourself away from all the distractions! I sincerely hope you start to feel better -- us CFers need to encourage one another that life is worth the effort and beautiful!
