I think you definitely have a purpose. I know how hard it can be, as I also have depression and a few other things, and things are easier said than done, but I believe you can get through whatever you're going through. You're strong, and you're loved by people that are willing to help you in any way they can. You may not think you're good at anything, but we are our worst critics. We usually don't like much of anything we do, but we can still learn to see the good in what we do. You have a purpose, but you might not know what it is yet. You're still young, and you have plenty of time to try things out. Opportunities can come to you in strange and unexpected ways. I know it's hard, but you must be patient.

Your worth isn't determine by what you are good at, you are enough. Even if you weren't good at anything (which, you are good at art!!) you would still be worthy of love and happiness!! You are awesome, even during times when you don't think so. You have lots of friends here that are ready to support you in good times and the bad!! <3

Who said you're not good at art? I've been trying to tell you for almost a year now that you and you're art are beautiful, don't doubt yourself, you are an amazing person and my life would suck without you, just please stop saying bad things about yourself *gives you the biggest hug in the entire world*
