I understand parents who don't get it
. Over the last 5 years my parent's understanding has improved considerably (with help from a support group and a therapist), but if they were to find out now that I "still" self harm, it would cause a great upset.
Are you currently living with your parents?
How about seeking support outside your family? They don't particularly need to know what's going on, if it will only be detrimental. How about talking to your GP and finding out what is available to you? If you get yourself some help before it gets too bad and you had to give up the job, you could manage without this episode disrupting your life entirely.
You're not a disappointment. It's disappointing your parents even think that. I missed a year of school and spent 18 months out before I started uni. In actual fact it is an achievement to make it to that point, as it is an achievement that you have a job. And if you think about it, they must realise you could have problems again as you finished your placement early, but still they want you to work for them.
To me it doesn't sound like the amount of treatment you received was enough to get you properly stable (as is too often the case). Do you have any notes or do you remember any of the things you learnt in therapy? I find it hard to remember my tablets, but I notice how bad I feel if I forget them too much. Using the alarm on your phone can help, or even just keeping them with you at all times... All the therapy and medication in the world can only work so well. It is important to stick with the treatment plan and put in the effort. And even after the sessions are finished to carry on with what one's learnt (much easier said than done...)
I'm away this weekend, but will be back online next week
Take care! x
