For one who has recently just gone through a really bad break-up, looking for activities to perk you up will be difficult. However, here are a few out-of-the-box ideas that would probably give you some respite. Just choose which would best fit you.
A Little Help From Friends – If you think that you can't manage to enjoy yourself without company, have a date with as many friends as possible. It doesn't even have to be a wild party too. Take an RV road trip, have a movie marathon of your favourite actor, or go to the AFL finals. Don't just hang out in your regular bar and watch a game on TV. Actually, buy some AFL finals tickets for everyone and have the whole gang treat you to snacks as everyone cheers your favourite team on.
A Night With Strangers – This may sound scary but it's actually not. Sign up for a city tour at your local tourist agency and just enjoy the trip with other travel enthusiasts. Buy a concert ticket of your favourite singer and enjoy the performance with fellow fans. Have fun with other co-enthusiasts simply just because of your fandom to connect you with everyone else.
Time Out On Your Own – For those who'd like to be alone but not be depressed, immerse yourself in a place or activity where you can't cry out loud. If you like to read, walk into a library and just go through books for the whole day. If you love art, visit a museum or several museums in one day. If you love nature, pack a picnic basket and find a spot in the park where you can paint, write, read, etc. Remember, you don't need to be lonely when you're alone.
Separation is a part of life. Of course, do cry still since that is also a part of healing. Just don't stick to doing that because here are a lot of other things you can immerse yourself in and heal.
