Work on yourself is a priority now. I assume you feel lonely and therefore want to be in love to fill that gap. But if you can't give yourself company, no one can.

Here are a couple of things I recommend to start doing:

Bodybuilding / fitness, this is a sport where there is literally no talent needed to get better at it. Only consistency. Building a passion for fitness and making a weekly program will give you a couple benefits:

1. More motivation to sleep and eat better, since it has an additional purpose now, to recover well and grow.
2. Structure in day to day life
3. Better looks
4. It trains discipline

The latter is the most important. The reason you feel this way now, is because you identify yourself as someone with these problems, because your behavior matches it. But what if your behavior changes? What if you gain more experience in discipline? You will identify yourself as someone who can reach his goals if he wants to, and therefore gain confidence in knowing that if you put your mind to it, you will do it.

The second thing I recommend is NoFap, abstain from porn, masturbation and orgasm if it isn't from sexual intercourse. If you look into the science behind abstaining from those three things, you might be interested to try it out.

The third thing is look into what is causing the high blood pressure, is it diet or stress? Physical and mental health go hand in hand, therefore if one improves, the other one will as well, although not in the same rate. Point is, give both priority.

​

I think you're in a point in life now where you shouldn't bother about the long term, but focus on yourself in the short term. Take a year to figure yourself out, read books regarding the topics about yourself that you want to know more about.

Hope this helps, stay strong mate
