You aren’t alone - Everyone goes through challenging times, they just don’t tend to advertise it. You can rest assured that your friends and family understand your feelings and will be willing to help you in any way they can.
It’s okay to cut yourself some slack - There’s no doubt that you will need time to experience all of the feelings that come about with a major life change. Give yourself a break from all the unimportant or non-urgent things that tend to fill up life. Just take it easy and heal your heart.
