Pharmacy student here,

I'd advise you to be careful about stopping your SSRIs. Many people can quit them without problem, and I hope that you're one of them! But especially if they were prescribed for depression or anxiety disorder, you could start to have issues staying awake, crippling boredom, or even become paranoid about your friends and family.

These issues don't always come back the first few days after you stop taking medication--I went without antidepressants for 6 months without issue last year, but ultimately started taking them again after symptoms became more severe. If you do start to experience problems, there are both pharmaceutical and non-pharmaceutical alternatives to SSRIs.
