is it hard to go back to the gym after an 8 month break

i need to go back to the gym in order to manage my diabetes type 2 and get fit....but ive not been over the winter months and beyond, because i lost drive and motivation...i realize i have to get back to the gym soon for my own health sake...th gym is just accross the road from me, but its still hard as i have low self confidence, ptsd and social anxiety.

will it be hard for me to go back? how can i? i never liked the gym environment to be honest and find it hard to go there.
