You're hurting, we've all been there but it's okay. I promise, there's a light at the end of that tunnel. I've been where you are, more times than I can count. But I always come out to a light on the other side. If I could, I'm sure you can.
You're a stronger person than you may believe right now, but that strength is there. Take deep slow breaths, focus on the happy times in your life. Open up to loved ones and friends so they can share some of your burden. They can be incredible sources of support. It gets better, you don't have to do this alone.
