I can relate with you, I was such a happy go lucky always joking around type of person, then I got to be negative all the time thinking of the worst, it does get better over time

Im finally starting to get in a better state of mind getting back to joking around almost enjoying myself although I still do have some symptoms lingering, I would have to agree to try to find something to get your mind off your ailment

I was miserable just stewing over what happened but there's nothing you can do about the past so I would say try to be positive about the future

I know that all sound cliche and ridiculous but it actually does help
