| ●Hi, Carolyn: It's been a bad time for my husband and me. I haven't been able to get pregnant since a miscarriage about a year ago, and many people around me have had babies or are getting pregnant. 1 I have been looking for another job for months and have been on more interviews than I ever thought I would get. But I still don't have a new position. 2 I know everyone has ups and downs, but I feel like I've been down so long, with nothing changing. How do you continue feeling hopeful when so many things go wrong? I've seen a doctor. She did help, but it still hurts when another friend is pregnant or wait another week with no job offer. -Feeling Down ●Dear, Feeling down: It will hurt, yes. And if you've lost hope, then analyzing the depression is a must. It's so personal that it's hard to make suggestions, but what are you reliably good at, what gives you great pleasure, and what puts smiles on your face? 3 For many it's just getting to the other side, knowing you have a favorite book or the person you love waiting for you at the end of the day. Personally, being a mom also comes with difficult lows, since all kids struggle with the world and with their parents. It's their job. While you say "so many things go wrong," I actually count two in your letter-losing your baby and your job. 4 But you do have your general health, your talents, your marriage, your friends, your family, and other abilities and interests to move you forward. 5 -Carolyn | |
