@Alifetimeofdiagnoises it’s because all your focus has been on getting to this point and you now have to change your focus. If this is a condition that cannot be cured, is progressive, invisible, chronic or poorly understood then it makes it even harder.
There was a thread last week from someone asking whether some illnesses are seen as more ‘deserving’ and unfortunately that is the case. Not because some illnesses are more acceptable than others but because anything that is long term, can’t be cured or isn’t that obvious to others is really hard for outsiders to understand. People can be empathetic to a point but, through no fault of theirs, can quickly tire of hearing about your ongoing problems and poor health. You quickly learn to limit how much you share and with who. It’s also very boring trying to explain/justify your health history and ongoing issues which is why a lot of people don’t talk about them much.
Whatever your diagnosis I would suggest looking for relevant support groups and charities. Mainly to get a full understanding of your condition, treatments, medications, alternative treatments, lifestyle adjustments, long term prognosis etc. I would then find a therapist - talk through everything you are worried about, the sadness of the life you planned that may now have to change, the guilt you feel for being perceived as a ‘burden’ to loved ones, the failure you feel of not being able to achieve what you once could, the frustration at the lack of support/treatment/understanding, the anger of ‘why me?’ All of these are normal emotions but they do need to be dealt with and getting external support is the most productive way of doing this.
Avoid comparing yourself to others with the same condition, everyone is different and has different levels of support, finances and health. Do not tell yourself ‘so and so has it worse so I should just get on with it’s, this may be true and help give you a sense of perspective but it in no way compensates or diminishes your own experience.
You will learn to ask for help when needed, to pace your energy based on your health, to accept this is the way things are, to adjust and create a new life plan. Ultimately you have to learn to be kind to yourself and appreciate your body is doing its best with the hand you’ve been dealt.
