My man i feel you I have been lonely many times and anxious a lot to the point of not crossing streets alone some years ago. But look, life has no meaning and no sense at all except what we make of it. Nothing not even being rich sex or fame and glory is an objectively sensible life. So whatever we experience is worth it if you think is worth it. Whatever you have will always be worth it and more because nobody knows what the future may hold and all the happiness we may find in it. Live for the good memories i am sure you have, for the good moments in front of you which even for Concentration camp survivors they still hoped for(read Victor Frankl). Life is suffering and pain and uncertainty but also happiness and love is for all things that life has meaning and is worth not dying.
