I feel compelled to respond to this as someone who has horrible anxiety, from the time of birth. Its okay, you arent condemned by God, youre loved. And your anxiety isnt even a automatic display of your spiritual progress as some have implied. You can be very spiritual, and still struggle. And honestly, I would love to see their whole life because im 100% sure that everyone here has at least one area where they are not fully "christian" in. My definition being this "christian like" sinless perfection, which is almost God level. I honestly doubt we'll ever get there here on this earth, though we all strive for it.
Anxiety and depression are hard. I wish that more Christians understood this! It seems that many dont, their words do not help in any sense. The lack of compassion and true understanding grieves my heart. They mean to help but they do not. I want to extend forgiveness towrds these people with compassion for their ignorance, sometimes its hard. Its the right thing to do though. Lord knows nobody knows everything, and really its honorable that they try to help.
It is worth noting that you are doing the right thing, depending on God through it. This doesnt mean youll find peace, or even feel it. But it does mean you'll have stability. God never leaves, and you have guidance. I dont know if ill ever feel peace, but I hope to one day. I pray very often, and read the Bible. These things have not healed me completely, because only God can, and despite my endless petition he has chosen not to. I still keep my faith, as do you and this is a wonderful thing.
My advice would be that you remind yourself of his love, his forgivness and compassion towrds you. Remember that hes not dissapointed or ashamed, and that he loves you unfathomably in ways you cant comprehend through these dark times. Continue trying to have faith through such difficult times, its important to keep our piety even through times of hopelessness. And remember, even when you don't slip, if you get burnt out as I do, God still loves you. Hes willing to accept you as you are and help you through to get to where you need to be. He will help.
As for being alone, its not good for man to be alone. We need people. We cant live completely alone. We are social beings. If you have good Godly friends, I would recommend you spend time with them, or even a pastor
Im not at the point where I trust many people, though im only 23 so I have time to continue to learn. My friends are few and far between but I do have a pastor i seek counsel from. This helps greatly. I also have an awesome husband.
Try not to rush being in a personal relationship with a person to fill the gaps of loneliness and isolation. But remember if you do, it can still turn out beautiful, honor God with everything you do and he can turn any situation into a better one. I married my husband after two weeks of dating( and two years of freindship) and it was rough at first but we are doing SO much better. We both want to honor God and seek to follow the God through his word faithfully. Have grace on yourself. And dont let others tell you whether or not youre where you need to be spiritually, consider their opinions but also be mindful that many times they're wrong.
I hope my advice can help, though these topics are so personal its so hard to know what will or wont help. And im sorry if I give more pain than encouragement.
