You sound like a very sensitive person.
In some way my circumstances are similar to yours... i was practically housebound due to depression rather than anxiety; i had no job (still don't have one at the moment actually, but i'm a carer so i can only work part time at the moment) and i had so little to get up for that i sometimes just lay in bed til after 1pm, sometimes getting myself upset. Like you, i seen no way out. I can empathise with how defeated and resigned you must be feeling right now.
Regardless of how lonely you must be feeling right now, you are not alone. There are others who understand how you feel because we've either been there or are still there.
The key to improvement is to take things in small steps; rather than daunting yourself by the totality, just make little steps one at a time. You'll soon start feeling you're making progress. For instance i go out at least once a week even if its just for a gentle stroll. Today i did just that by choosing to walk to the post office. It breaks up my day, improves the oppressive feeling of depression in my mind. I've also started taking up hobbies i ditched for the last few years as i resigned myself to a pit of darkness, such as reading, coin collecting, etc. Encouraging yourself to pick up old interests, or find new ones, definitely helps. Starting with little goals like that, achievable and spirit-raising, do help believe me. They're the stepping stones to further progress and purpose in our lives.
This year i plan to start looking seriously for employment - i have been employed before in the past but this will be my first one since anxiety/depression struck me with the force it did a few years ago. From just the prospect of finding employment i already feel my self worth beginning to rise.
And maybe you are alone right now, with no friends or anything... but the amount of friends we have is no reflection on who we are our what we are worth.
There are people who have plenty of 'friends' who are feeling very alone right now. I used to have alot of friends once upon a time but they all disappeared when my anxiety and depression struck me down, except for one who proved his worth. And i feel a whole lot richer for knowing i have one true friend in the back rather than a batch of fair-weather friends. Anyway, there is always time to make new acquaintances and friend in life. We all need to realise that we have inherent self-worth regardless of what others think of us. From your erudite post here, i can tell you are no retard, CNikki.
And at the very least, you can write your feelings out here. A nice, anonymous, safe ***** for you to express yourself.
If you wish, i'm sure people will take the time to read and respond.
This in itself, this post you've made, is a small step. It shows you want to reach out and you want to bring change into your life. You can do that, and i'm sure folks here will be happy to encourage you. Some people almost turn this sort of thing into a progress diary, then later they can look back and see just how far they've come, realising just how strong and capable they are and gaining even more confidence in themselves.
I hope that you find the support here that you're looking for.
