I agree with most of the guys here, you surely are not in a good position, agree on that.
Being bald, overweight, out of shape and in your 40s surely is not the best setting to pick up women or change your body rapidly.
However you can fix it which is totally at your reach, first of all drop any sourch of negativity in your life either those channel where sadic women bash men only to become sensitive while talking about them.
Not sure how is your wallet however subscribing to a gym is a necessary step, dont bother to revolutionize your clothes before transforming your body, it will be the new you to fit the right clothes and it will be your new you to chose a style that fits to him, no military campaign has been done in a week neither will be your personal one.
Regarding the low testosterone, find the reason for that either is your diet and habits or a physical problem, have a talk with a doctor and consider TRT if a solution to bring back your test cant be found, this is important you can do shi1 without testosterone, its the first drive of a man 360 degrees.
Also you do have some strange vibe, your facial expression in your pictures show it, its not a matter of look but of attitude...hit the gym, build yourself into a new you and such expression will change so will your body language.
Also something I shouldnt tell you considering how guys with problems operate in the us, at your point your life sucks and is miserable so just do whatever it takes to change it, you basically have nothing to lose.
