dude wat ur feeling is very normal and alot of people feel the same way. one thing that ive really noticed lately is that people all seem normal and happy on the outside but EVERYBODY has got their problems and issues. i know several people who are feeling down and lost for the same reasons u described but that is life dude. everybody have their own reasons to keep going.

look, you never know what will happen in the future and you may either find ur purpose or it will find u. ur just going through a rough patch that most, if not all people go through.
