I usually only check the forums a few times a week during the later part of the evening, so I'm sorry I didn't see your plea for help sooner. I understand how anxiety and sadness kicks in at night. I feel that way every night, which is when I am most depressed (hence my user name). I think that's why I come on here at night, so I can post and communicate with others. So if it is any help, please know that you aren't alone in your loneliness.
I think you are doing a great job of trying to be proactive about
meeting new people and making plans with friends. I'm just sorry that this hasn't been easier for you. I sometimes wish we all lived closer to each other so we could all socialize! Sometimes even if I'm by myself, I feel less lonely if I'm around a lot of other people at a bookstore or a lecture. Are there any things like that happening near you? Sometimes getting on e-mail list to be updated of those things is good. Or sometimes I'll even go to a movie by myself or do my grocery shopping in the evening, as long as it's not too late or dark...safety first! Anything to get me out of the house. It's often easier for me to come home to an empty house if when I feel that I got out and learned something new or did something enjoyable.
If I don't feel like leaving the house, I sometimes do workout videos at home, which make me feel really good when I'm finished because I'm full of endorphins and feel relaxed. Also know that your boys will be back before you know it.
I'm so glad to hear your son is feeling better through therapy. You helped me very much so that I know I can heal from my broken heart. I'm still struggling a lot but I have faith that I'll feel better with time.
We're here for you!
