I understand what you're saying.
But sometimes you just have to push yourself to try to achieve what you want to do (it's not easy, for sure, if the mentality is the fear of not achieving or rejection is holding you back) - the hardest part is picking yourself up.
On the work front: I'm currently unemployed after 2-and-a-half months, with a few interview 'rejections' which have hit me more hard than I thought it'd do, but as hard as it is having to deal with rejections - I know that I'm one step closer perhaps to getting something.
My partner is visually-impaired, and had to deal with many interview rejections for 9 years (and having to work during this period with a company that overlooked her in many cases due to her disability) - but she's got a job in the NHS now, which she really wanted for a good while.
So, anything is possible despite setbacks and think the key aspect here is a positive mentality.
Good luck.
