You won't find support here to help kill yourself - that is against the whole reason the forum was established. It is 'Pro-Life' - which is not some wacky religious take on life - just basic common sense.
Some people have reasons to die - terminally ill people perhaps with no quality of life - but with depression, you understand that suicide forums like this have to make sure that the people who post here get along also - as much as we can.
Sometimes you come across as angry - which is not an issue for me, but when your anger is directed at yourself it only makes things worse.
It is a real shame your parents cannot deal with you being bi sexual - some live in another age I guess.
Living at home aged 23 is not unusual - in fact it is more common now because the cost of renting is so high. I know many people who live with parents because its a good way to combine resources. Plus, you are there to help parents especially as they get older.
Moving out is a good move for many but you need a decent job first and its no use feeling the blues over not having a job - you got to just use your resources, learn more things so you have skills to trade with people.
If you have no job - you have lots of time. I know its not easy to sign up for courses but you have home study courses - or ones were you attend somewhere just to pass in the work.
As for forum access only - I'm sure you will be given full rights. It takes a few posts before you can let loose - others also have hundreds of posts but 'forum access' - maybe some lose it from time to time.
Maybe you've said a few things in anger - I know not - but you seem an angry young man - and really, the problems you are angry about are OTHER peoples problems. Their prejudices are not yours to carry - and my advice, re the family, is to try not to fall out big time with them. Tell them you love them - but your sexuality is just something that is part of you. You cannot help it anymore than you can help liking ice cream of a certain flavour. You fancy men as well as women - which I suppose gives you a head start in finding someone suitable.
To be honest - if you don't mind if it is a girl or boy - maybe a women would be better because - well, they tend to make us feel better - they are a balance in our lives, if we choose the right women or the right women chooses you.
Then again, having another man might be easier - as you will always agree to go out for a beer and so on. No arguments about soap operas either, or is there? Not sure really - just being nosy I suppose.
So, forget any prejudices others might have - forget about yourself being 'nothing' and not worth the bother. This is depression playing its usual tricks - selling you a dud version of yourself and holding it up as a means of belittling you.
You have some depression, which might feel like the end of the world but its not really.
Hope you can get some help with it - also, maybe a move to your own bedsit or something would allow you your own space to what you want. Some time to think about life choices without having your parents peer over your shoulder.
Good luck and do try and get some help - or let us know what you are doing.
