Hi norris,
I was bullied a lot at school and believed that I was ugly and worthless, it's taken a lot of years and plenty of therapy for me to realise that I'm not either of these things. At 23 I was still massively underconfident, and had only had I boyfriend, who treated me with the same lack of respect I treated myself with!
The first thing that I notice in your post is that you seen to have attached physical looks and having a girlfriend to value and worth. I think it is these beliefs that are causing you pain, rather than your looks alone. Have a think, are there any people of value and worth in the world who are also plain or even ugly or disfigured? (Have you seen the film Shallow Hall? If not I highly reccomend it)
When I first met my DH my first thought was not "Wow what an attractive person" in fact he wasnt even my usual 'type' my first thought was "He seems like a nice person" 10 years on and to me he is the most attractive person in the world, because I love the person that he is, that is what makes him handsome to me. Its no good being beautiful on the outside if you are ugly on the inside.
Next point they have girlfriends and live happy lives full of pleasure Do you know any unhappy people who are in relationships? Being in a relationship doesn't necessarily make you happy. In fact I would say that you need to develop a good relationship with yourself first before you can expect to have a good relationship with others. We only ever see the outsideof ppeople's relationships, the bits they want us to see.
I want to be a normal 23 year old and go out with friends every night I was definately not going out every night at 23, I was working full time, living on my own and spending most evenings at home alone keeping up with housework, gardening etc and so were my friends of a similar age.
It sounds like right now you are in a very black place. If you are feeling that you may harm yourself I would urge you to go to A&E. Also samaritans are always available to talk to or email. I think it can be very hard for young men in our society to discuss their feelings and emotions, bbut I'm sure thereare many others who feel similar check out Andys Man Club on Facebook. I would also advice you to see your GP, maybe print out your post to show them if you struggle to know what to say. Don't worry, your GP will have seen plenty of people in similar situations before.
I'm sorry you haven't had a good experience with therapy so far. There are different types of therapy and your GP will be able to discuss various options with you.
