The starting point is that if you have been continuously employed at your place of work for less than 2 years then your employment rights will unfortunately be somewhat limited. Most importantly, you will not be protected against unfair dismissal or constructive dismissal. This means that your employer can dismiss you or force you to leave for more or less any reason, and without following a fair procedure, as long as their decision is not based on discriminatory grounds (i.e. because of gender, race, religion, age, a disability, sexual orientation, etc.) or because you were trying to assert any of your statutory rights (e.g. requesting maternity/paternity leave, etc.). In the event that the reason for dismissal fell within these categories, then the dismissal will either be automatically unfair, or there will be a potential discrimination claim.
So the main issue here is whether you can argue that you have a disability as that would be the best protection you can get in the circumstances. There are specific elements you must satisfy to be deemed disabled and if you do then you will have rather strong protection, in a sense that they cannot treat you detrimentally because of it and they would also have a duty to make reasonable adjustments to help you cope in the workplace.
This is your basic legal position. I have more detailed advice for you in terms of the law on disability and how to determine if you are disabled, which I wish to discuss so please take a second to leave a positive rating for the service so far (by selecting 3, 4 or 5 stars) and I can continue with that and answer any further questions you may have. Don’t worry, there is no extra cost and leaving a rating will not close the question and we can continue this discussion. Thank you
