Newly diagnosed ADHD and ASD

Hi my name is Carl, I am 44 years old single male work full time as a delivery driver and I am newly diagnosed as above and I thought after the diagnosis things would suddenly become easier bu to after 3 weeks it now seems to me that im fact it is now tougher than before as I seem to have exhausted the will to keep seeking info and potential help or guidance and have hit an all time low, all the help really suggests is to join various communities and join with others in a similar position but if I am honest the socialising aspect. Keeps me avoiding things and now I begin to feel as though there is no hope and that I will carry on regardless in this pointless existence under the same daily pressures avoiding the same things sticking to the same safe places and routines until I guess the end which honestly I have no concept of when that could or would be, I am kind of just venting because if I don’t write it down as I am thinking it then my mind moves on and the thought is lost so thanks for taking any time to read any or all of this and if anyone has anything to respond with either good bad or otherwise then please do as I will not be offended in anyway but possibly a different perspective on things may help enlighten me or maybe just change one point of view

many thanks 

Carlos
