1) some awesome friends to lift you up when you're down.
2) to know that someone's always there for you and understands your pain.
3) thoughts of better times and/or memories.
But sadly it's not that simple.
No matter how many friends you have, You could always have the doubt that you don't really fit in. Or that 'you're too ugly to be with them'. Or that they don't actually care.
Someone might 'always be there' for you, but eventually, they'll grow old of the same things over and over again and just move on. They say they understand your pain, but they'll leave because they already have too much to handle.
And no matter how good the memories you'll forget them. No matter how much you miss the people in them you can't see them. No matter how happy you were in them, looking back will make you sad. Trust me I know.
It's not that simple to be happy. Never was, never will be. Some people just aren't made to be happy.
Some people, like me.
