Get over your crush by distracting yourself with activities that make you feel happier. For example, try a new hobby, call your best friend, go out and make new friends, or do something else to keep your mind off your crush.
If thoughts about your crush have become that intrusive, it is likely you are suffering with limerence. This is a mental state of obsessive infatuation that is characterised by intrusive thoughts that you just can't seem to turn off.
Don't lose yourself in laughter or tears; keep it together and try not to convey too much emotion. Be aloof and detached whenever you're talking to someone. Don't talk about yourself. Keep some distance from those around you by not saying too much about your thoughts, feelings, habits and personal life.
A crush could either develop or dissipate depending on the level of attraction. A crush could last a day and fade away or months and then progress into something deeper—it will all depend on how deep your attraction is with the person.
The reason you can't get over your crush is that you have accidentally trained yourself into a mental habit of constantly seeking them. The excitement and euphoria of that initial romantic connection makes them the central focus of your life, and because it feels so intoxicating and good, you don't resist.
If you're someone who spends too much time imagining that 'perfect' person and you want to break that pattern, psychologist Dr Jarrod White says you should first accept that this behaviour is normal. "It's something that a lot of people go through."
One sign that this is more than a crush: "Your feelings don't dissipate over time but get stronger and deeper," says Irina Firstein, LCSW. So basically, if you've been feeling this way about your special person for a looong time, it's definitely possible that you're in love.
Obsessing over a crush floods our brains with feel-good hormones, so it can be “a little addictive,” she says, and a hard habit to break. However, over-indulging in fantasy is not so great for a number of reasons, and it can be helpful to remind yourself of that next time you start fixating on someone.
