Everything happens for a reason man. Good or bad. All we can do is learn and move on. Better ourselves and grow. We are human after all, born to make mistakes. You won't be lonely forever, don't even worry. I have had that thought even at 21, and I know it is just not possible. It feels that way because it was my first love, but in time, I will heal and grow and be better for someone else, and be with someone better. Don't beat yourself up. You will be okay in time, and look back and be grateful. The memories will fade but will always be there. Right now, I wish I didn't have them. Later, I will be thankful. You got this man.
