I hope you're feeling better today. Some days are easier than others, for all of us, it's only human. However, it can be very difficult, when we're not finding enjoyment we all need. The things you used to enjoy with your husband, you are being asked to endure, for a time. Meanwhile, the Spirit is telling you to reach out, and I'm glad you have.
People are deeply social beings. Adjusting to life without our loved ones is the most difficult process. Losing a spouse feels worse than losing a limb; you have been separated from a man that brought you very close to heaven. In some ways, withdrawing socially gives us a way to ponder and reflect. In others, we find ourselves dwelling on our past. There is nothing we can do to change our past; there is only looking forward. When we look forward to His promises, we have Hope. He is our greatest example of Charity, to know He Loves us so much, that He sent His Son.
Until you arrive at your heavenly estate, you are going to miss your husband. It's okay to miss him, there is nothing at all wrong with that. You are Faithful, even knowing, that your husband will be there, patiently waiting for you. Just don't rush yourself, our Father works on a clock we can't control.
Remember that you aren't truly lonely. He listens to you, in good times and bad, even when you're feeling like your choices push Him away. He knows you need Him, every hour, in joy and in pain. Don't feel ashamed when your pain brings you to tears. Your self-image isn't how He sees you. Your spirit is beautiful, and even when we can't see that in ourselves--He does! If you take on healthy habits, such as proper diet and exercise [your doctor needs to be in charge of this part]; you will find that they can do wonders for how you are feeling. Even with your husband being away, there is no good reason to hurry.
Each time you look in the mirror, don't be ashamed to have a conversation with yourself. Debate with the opposition within yourself. Psyche yourself up. Don't let your doubts have control over your actions. Let your confidence strengthen. Doing so can help you make better moral decisions. If that's too embarrassing, meditation is also very helpful. Find the younger part of yourself that decided this is who you are. Tell yourself what was wrong about those choices. Wrestle with those feelings of resentment, of doubt, of resignation. Don't simply think you can overcome everything by yourself. Ask our Father in heaven, in all cases. Know that He is the Lord of your soul, be faithful that He does provide; let His Spirit be with you. If He sends you a shoulder to cry on, an ear to hear, or a message to bear--let them in and ask your pride to leave. By the same token, don't be too ashamed to seek out what you are in need of.
