Loneliness is the worst enemy imo. We are social beings and being deprived of friendship, etc drains us. Try to find a hobby that you can participate during your spare time. Even better if it is physical. Maybe you played in some sport when you were younger that you can take up again? If we have a good social network (irl and not online) all the other things will come easier have I noticed. I beliebe that you can make it. Just hit me up if you want to discuss things further. I am M22, so I am around the same age too.
