i take sertraline but everybody is affected differently. talk to a doctor. the internet is full of armchair experts and attention-seekers, don't bother looking into their advice. go to several doctors if you have to, 5 doctors are better than a million internet ppl.

if you physically can't talk, look into selective mutism.
my opinions in life are not popular, but they work for me. solve your problems from the root. the pills ive taken have drastically reduced my anxiety, obsessiveness, sensitivity and libido. i was never able to get a girlfriend, and the truth is i still cant. im as ugly and eccentric as i was then, the only difference is now i dont care. going from depressed and anxious to empty and apathetic is an improvement. killing yourself out of boredom is less tragic than killing yourself out of despair.
dont be a slave to the anxiety and desire and try to please it with women and acceptance, rather try to eliminate the desire from the root. you are much better off having nothing and wanting nothing than wanting everything and having nothing. the universe is indifferent to your plight, it will not reward your effort or feel sorry for you.
i understand your situation damiancopado, suicide is actually a pretty good idea, but do it on your terms and on your schedule. don't let your despair control you. you may not ever be positive or happy, but going from negative and despressed to neutral is a huge improvement.
whatever you choose to do, make sure you do it with a clear and unbiased mind. right now you cant do that. take the pills you need to get rid of your emotional and mental biases, and then search for what you really want.
